AB  - ABSTRACT
In this paper solution of a non-stationary one dimensional (1D) heat conduction problem has been presented. The finite difference method, i.e. by applying energy balance has been used. The finite difference method has been applied and the partial differential equation of heat conduction has been reduced to an algebraic form. This procedure is also called discretization problem. By solving the system of algebraic equations, temperatures at discrete points - network nodes were obtained. Additional discretization was performed in non-stationary processes over time. Numerical 1D non- stationary calculation was performed on six walls of different thickness made of aerated concrete 50 mm, 75 mm, 100 mm, 120 mm, 150 mm and 250 mm thick are exposed to the developed fire. The developed fire represents the logarithmic dependence of the temperature as a function of time according to the standard SRPS EN 834-1. The period of wall heating was analyzed, i.e. period until the moment when the temperature rise is observed on the non-exposed side of the wall. The paper compares the achieved experimental results with the obtained numerical results.

AB  - ABSTRACT
In this paper a comparative analysis of thermal behavior of six partition walls with different thicknesses were presented. The walls were dimensions 3000 mm x 3000 mm made from autoclaved aerated concrete blocks with dimensions 625 mm x 200 mm and thicknesses 50 mm, 75 mm, 100 mm, 120 mm, 150 mm and 250 mm. All walls were exposed to standard fire test according the standard SRPS EN 834-1, non- combustibility test according the standard SRPS EN 1182 and surface spread of flame test according to SRPS U.J1.060. All walls were tested to fire resistance in vertical furnace with a data acquisition system, according to standard fire test. Standard furnace for testing construction consist of four two step burners in liquid fuel type „Major P25 AB HS TL V.C.“, heating power of 296 kW manufactured by ECO FLAM. Two transmitters of differential pressure type 6321 manufactured by TESTO (Germany), with range
 +/- 100 Pa installed inside the furnace were used for pressure measurement. Inside the furnace the temperature on six places with thermocouple type K were measures. The measure ranges of thermocouple type K were -270 0 C to 1372 0 C. The temperatures on
unexposed fire side were measured in nine places with thermocouple type T with measure ranges -270 0 C to 400 0 C of according the national standard SRPS U.J1.090. The obtained temperature results depending of the time of reaching the critical temperature were presented for each wall thicknesses. The five identical cylindrical samples with high 50 mm and diameter 45 mm for non-combustibility test has been used. All samples have been tested in standard furnace for non-combustibility test. The
average temperature in furnace and specimens were presented. Surface spread of flame testing is carried out according to standard SRPS U.J1.060, if the coating material is based on organic or mixed materials. The samples for these test are with dimensions 900 x 230 mm.

AB  - Abstract
The growing expansion of construction and import of new, as well as existing materials from around the world, has led to a large number of tests materials and elements of constructions in the Republic of Serbia. Most of these materials and building constructions have test certificates obtained in foreign laboratories, which mostly refer to European standards. The currently valid Rulebook on mandatory attestation of elements of standard building structures for fire resistance and on working conditions that must be met by organizations of associated labour authorized to attest these products from 1990 requires testing of each product, or structural element, according to the domestic SRPS standards. The condition for accessing the European Union requires the harmonization of regulations related to the testing of construction products. Therefore, the IMS Institute, the Ministry of Interior - Sector for Emergency Situations and the
Ministry of Construction of the Republic of Serbia have written a new draft Rulebook on
Technical Requirements for construction products for which performance characteristics are
important: reaction to fire, fire resistance and external fire performance. The plan is to publish
the Rulebook, as valid, at the beginning of 2022, with a transitional period for implementation
of two years. The paper presents a overview of the new Rulebook.

determined experimentally. The problem of determining the thermal conductivity
in the soil is greater because the soil is heterogeneous, so for the same soil this
parameter may be different depending on the their ohysical characteristics.
Therefore, it is necessary to adopt an appropiate model for describing the thermal
conductivity of the soil for a particular location after the necessary tests are
performed. This paper is based on experimental measurements of soil thermal
conductivity as a function of moisture content in the area of the ,Nikola Tesla
Airport construction site in Surčin and the adoption of one of the existing
theoretical models that would satisfactorily describe changes in thermal
consuctivity. Based on the obtained results of experimental reasearche, a two-
parameter fitting of the measured values of thermal conductivity of the soil was
performed in Cote-Konrad model, which proves to be reliable and the simplest to
describe the thermal properties of loess in the area of Belgrade.

AB  - The guarded hot plate (GHP) method is a widely used technique to measure
thermal conductivity of thermal insulation specimens in steady-state conditions.
In this paper, an advance of GHP has been developed in the Laboratory for
Thermal Technique and Fire Protection in Institute IMS. The innovative GHP
has been applied for measuring thermal conductivity using additional heat flux
meters. The design of this GHP is similar to the design of the plate for GHP apparatus, however, it has different design: smaller width of thermal barrier, which
is filled with insulation glue. Heaters inside hot and guard plates are built from
wire for thermocouples, which is a unique type of heater. Geometry of heater has
been optimized inside plates to achieve uniform temperature distribution along
the specimen surface. Temperature uniformity of GHP and energy balance were
experimentally determined. The verification and validation results of improved
GHP have been shown. The test method was validated comparing test results of
thermal conductivity with results of the round-robin test. Four national companies participated in the round-robin comparison on thermal conductivity measurement by GHP method. The measurement was performed on the same specimen
of thermal insulation material (expanded polystyrene) according to SRPS EN
12667 at temperatures ranging between 10-40 °C. The measured thermal conductivity of all participants in the round-robin test was input data for statistical
processing according to SRPS ISO 5725-2 and ISO 13528. To evaluate the performance of the participants, the “z” score has been used. Measurements were
conducted successively for all participants. Since 2020, the Accreditation Body of
Serbia also approved this test method.

is filled with insulation glue. Heaters inside hot and guard plates are built from
wire for thermocouples, which is a unique type of heater. Geometry of heater has
been optimized inside plates to achieve uniform temperature distribution along
the specimen surface. Temperature uniformity of GHP and energy balance were
experimentally determined. The verification and validation results of improved
GHP have been shown. The test method was validated comparing test results of
thermal conductivity with results of the round-robin test. Four national companies participated in the round-robin comparison on thermal conductivity measurement by GHP method. The measurement was performed on the same specimen
of thermal insulation material (expanded polystyrene) according to SRPS EN
12667 at temperatures ranging between 10-40 °C. The measured thermal conductivity of all participants in the round-robin test was input data for statistical
processing according to SRPS ISO 5725-2 and ISO 13528. To evaluate the performance of the participants, the “z” score has been used. Measurements were
conducted successively for all participants. Since 2020, the Accreditation Body of
Serbia also approved this test method.",

AB  - Abstract
Testing the clay hollow-brick masonry non-load-bearing wall helps us to understand the
behaviour of this type of wall during a fire. It is important to know the fire resistance of hollow brick walls so that we can prevent the fire from spreading to other rooms. In this paper, the experimental analysis of fire resistance of non-load-bearing wall with dimensions 3000 mm x 3000 mm thickness 200 mm were presented. The wall was made from clay hollow-brick masonry blocks with dimensions 500 mm x 200 mm x 249 mm (L x D x H) with mortar on both side of wall of thickness 15 mm. The wall was exposed to a standard fire test according to SRPS EN 1363-1:2014. The temperatures on the unexposed side of the wall were measured in thirteen positions with thermocouples (K – type) according to the national standard SRPS EN 1364-1: 2014, and at the junction between mortar and clay hollow-brick. Deflection of the wall in five places was measured also. Obtained results depending on the time of reaching the critical temperature during the fire test were presented.

AB  - Summary: In this paper the experimental results of two-dimensional non-stationary
temperature fields of prefabricated ferrocement sandwich panels in fire condition, were
presented. In order to determine resistance to fire, the temperature fields of two walls
dimensions of 3000 mm × 3000 mm and a thickness of 190 mm made from precast
ferrocement sandwich panels, were analyzed. The first panel has been insulated with
styro-concrete, and the second with styro-concrete and expanded polystyrene. The
panels were exposed to conditions of real fire corresponding to the standard fire curve
defined by the standard SRPS EN ISO 834-1. The tests have shown that, due to the
detonations that occur when the panels are exposed to fire, these panels have
unpredictable behavior.
