... experimentally investigated. Tested specimens were prepared using 0%, 5%, 10% and 15 wt.% of limestone as a replacement for OPC. The fire-resistance performance of the prepared rendering mixtures was evaluated through their residual strengths, X-ray diffraction, thermogravimetric analysis (TGA) and scanning...

... strength in 28 days. It is exposed to heat to reach 600°C and kept for one hour. Tensile and compressive residual strengths are determined and compared. Findings Before heat strengths of concrete containing micro-silica and propylene are higher than those of conventional concrete (63% increase...

...-standard fire exposure. Design/methodology/approach The first set of experiments was performed as a benchmark to find the load-carrying capacity of the assembly and investigate the failure modes at AT. The post-fire performance (PFP) test was performed to investigate the residual strength...

... to a non-standard fire on the residual strength of the assemblies. The assemblies were exposed to fire in a custom-designed frame, then cooled and loaded to failure. A fire performance (FP) test was conducted to study the fire resistance (FR) during non-standard fire exposure by simultaneously applying...

A fire-performance test was conducted to investigate the fire-resistance during non-standard fire exposure...

... blocks satisfy density and compressive strength requirements for loadbearing lightweight solid masonry units. Fire resistance of the composite block is –/120/120, and no cracks appeared on the ambient side surface of the block after 3 h of fire exposure. Residual strength of the composite block is higher...

.... It is shown that an increase in the degree of confinement reinforcement results in an increased residual strength and deformability of pre-damaged confined concrete. Research limitations/implications It is applicable in finding the residual strength and strain of the pre-damaged confined concrete in uni...

.../approach Two mixtures were developed to test. The first mixture, OPC, was used as the control, and the second mixture was HPC. After 28 days under water (per Chinese standard), the samples were tested for compressive strength and residual strength. Findings The test results showed that at elevated...

.../binder ratio of 0.36 and grade M40 were prepared by using ordinary Portland concrete alone, or with partial replacement by fly ash (FA), blast-furnace slag, silica fume (SF) and a combination of all three. After 7 and 28 days under water, their strength and residual strength were measured. Findings...
