  • Finishing materials are very important to restrain fire spread from a compartment to another in a fire situation. Therefore, the evaluation of combustible properties for the combustible material is essential to apply finishing materials into a generic buillding or s special occupancy structure. In this study, the testing methods for evaluation of combustible performance of finishing materials of domestic were surveyed in order to prepare the guideline of application of finishing materials in nulear power plant.

  • Recently, "The rules on the standards of evacuation and fire protection of buildings" require that non-burnable materials such as non-combustible and semi-non-combustible materials be used as the materials applied to the building's exterior walls, but styrofoam, which is a combustible material, has been applied a lot and became a social issue. In this study, we developed a non-combustible outer wall molding to secure construction and economic feasibility and free expression using CLC(CLC: Cellular Light-weight Concrete).

  • The organic insulation material has excellent thermal insulation property, but it is difficult to expect fire stability, and semi inorganic insulation only delays combustible hour but it is difficult to expect fire stability. In this study, thermal insulation property of cement-based non-combustible inorganic insulation using cement and non combustible materials and redispersible polymer powder was studied. As a result of the experiment, the thermal insulation property decreased as the use of redispersible polymer powder increased, but the heat insulation property improved when using the appropriate amount.

  • A series of fire tests involving realistic solid combustible materials was conducted to quantify the heat release rate and investigate the fire growth characteristics during the initial fire growth stage. For these tests, single/double wood cribs, urethane cushion having polypropylene covers and wood crib on nylon carpet with urethane carpet padding were used as a fuel source. The fire growth coefficient of the solid combustible materials was quantified and the fire growth characteristics were compared with the $t^2$ fire scenario. The mean effective heat of combustion was evaluated by the total mass loss of fuel and total energy release concept and examined the effect of the ventilation and fire condition. The present study provides the practical information on the fire growth characteristics of solid combustible material to design to a set of fire scenarios for the fire risk analysis.

During a fire, toxic gas that is generated varies depending on the combustible material occurs. However, all combustible materials, including carbon, incomplete combustion of carbon monoxide which is generated in the most common toxic gases can be seen as one.

  • External fire spread has the potential to breach vertical compartmentation and violate the fire safety strategy of a building. The traditional design solution to this has been the use of non-combustible materials and spandrel panels but recent audits show that combustible materials are widespread and included in highly complex systems. Furthermore, most jurisdictions no longer require detailing of spandrel panels under many different circumstances. These buildings require rapid investigation using rational scientific methods to be able to adequately classify the fire risk. In this work, we use an extensive experimental campaign of material-scale data to explore the critical parameters driving upward flame spread. Two criteria are outlined using two different approaches. The first evaluates the time to ignition and the time to burnout to assess the ability for a fire to spread, and can be easily determined using traditional means. The second evaluates the preheated flame length as the critical parameter driving flame spread. A wide range of cladding materials are ranked according to these criteria to show their potential propensity to flame spread. From this, designers can use conservative approaches to perform fire risk assessments for buildings with combustible materials or can be used to aid decision-making. Precise estimates of flame spread rates within complex façade systems are not achievable with the current level of knowledge and will require a substantial amount of work to make progress.

  • In Korea, buildings are becoming skyscrapers due to restrictions on land. The performance-oriented design was introduced in 2009 for fire safety of such buildings, but the application of the combustible data through engineering design and experiment is a poor reality. Large buildings are used for complex purposes, especially since the density of the office facilities is high, the study conducted a study on the combustible materials of the office facilities and the thermal speed and fire load of the main combustibles of the office facilities were calculated.

  • It is needed to classify the kinds of construction and demolition(c&d) debris to 6 catagories of waste concrete, waste asphalt concrete, waste wood, scraps, combustible waste and incombustible waste in order to properly do a separate discharge and to estimate unit generation rate in construction site. Also, in this case, the unit treating cost for mixed wastes should be applied with the unit treating cost for combustible waste. The construction standard materials estimation data is used for basic data for estimating unit generation rate. The mixed wastes in this data should be classified to waste wood, combustible waste and incombustible waste, and their ratio is obtained by using the unit generation rate of Asia Pacific Environment and Management Institute and Seoul Metropolitan Development Institute. The waste amounts generated from newly-built construction can be obtained from multiplying the loss rate by the amount of materials used from construction standard estimation data. Also, those from dismantling construction can be obtained by subtracting waste amount generated during newly-built construction from total input amount of materials in newly-built construction. Those in two cases can be used in construction site. It can be used for estimating the amount generated and establishing the treating plan in the case of setting up the policy of waste management and doing the environment impact assessment.

  • The purpose of this study is to develop an organic-inorganic hybrid insulation materials which has an economic feasibility of organic level and excellent adiabatic performance and fire stability by impregnating organic materials with inorganic binder solutions. The organic base was commercial polyurethane sponge, and the inorganic binder slurry was prepared by mixing water and additives into recycled gypsum byproducts. As a result of evaluation of the developed materials, it was confirmed that it not only has excellent insulation performance of a thermal conductivity of 0.051 W/mK or less but also it is a semi-non-combustible materials specified in the Ministry of Land, Infrastructure and Transport Notice No. 2015-744. The developed materials can also be controlled for thermal conductivity and flame retardance according to density control during manufacturing process, and thus it can be applied to various insulation materials.
