“…These results indicated that the higher thermal stability of the MDF resulted in a milder degradation of the MDF (Becker et al 2011). In addition, the existence of EV could improve the antioxidation property and the thermal stability of char, due to its higher aspect ratio of silicate layers (Xue et al 2015).…”

This study investigated the effect of expanded vermiculite (EV) on the flammability properties of medium-density fiberboard (MDF), which was evaluated by limiting oxygen index (LOI) and simultaneous thermal analysis (TG-DSC). In addition, the modulus of rupture (MOR) and the modulus of elasticity (MOE) of the samples were studied. The results indicated that the addition of EV increased the LOI of MDF, while it decreased the MOR and MOE of MDF quite rapidly. The TG data showed that the fiber-charring rate of the fire retardant MDF increased sharply, more than 10 times that of untreated MDF. Moreover, with increasing of the ratio of the EV and fiber (V/F), it increased the fiber-charring rate of the MDF sharply, decreased the temperature of the maximum mass loss, and decreased the maximum mass loss rate of MDF. The DSC test results indicated that the total temperature range of the exothermic stage had extended and that the first peak in the exothermic stage decreased rapidly with increasing of V/F ratio.

Steel structures are widely used in modern construction in various structural forms. In particular, steel structures are common in quick prefabricated buildings. These are industrial and agricultural facilities (woodworking shops, warehouses of building materials, granaries, poultry farms, greenhouse), garages for special equipment, sports and recreation complexes, exhibition and entertainment centers, shopping pavilions, office buildings, etc.

“…Reasonable fire-safe design can reduce fire-caused damage to building structures [6,7], prevent a dramatic decline in the material intensity of the building structure over a short duration due to high temperatures, and avoid consequent destabilization and destruction of the overall structure, thus, minimizing possible loss of human life and property due to fire and reducing the restoration cost of the building structure after the fire [8,9].…”

To promote and criterionize the application of ultra-thin the fireproof coating s to building structures, four concrete-filled square steel tubular (CFSST) pillars as well as two square steel tubes, each protected along with ultra-thin the fireproof coating , were subjected to full-scale fire tests to investigate their fireproof level on the basis of the ISO 834 criterion time�degrees curve. Test results revealed not only the temperature variation characteristics of specimens suffered from inconsistent fire exposure, but also effects of the steel ratio of the test specimen and the number of fire-exposed sides on the fire-refractory level of the test specimen. Test results demonstrated that when protected with an ultra-thin the fireproof coating , the heating rate of the specimens was considerably lower than that of the test furnace, suggesting that the ultra-thin the fireproof coating exhibits good thermal insulation performance. The test results were compared with China�s current criterions for the fire-refractory level of square steel tubes and CFSST pillars, indicating that the criterions would lead to a relatively conservative fire-safe design for four-side fire exposure.
