Eco-friendly fireproof high-strength polymer cementitious composites

The cementitious fireproof material is widely used to protect concrete structures against fire. However, there has lately been interest in developing more environmentally friendly construction materials that have lower cement content, since cement manufacture has a large carbon footprint. One approach, formulated here, makes use of eco-friendly fireproof high-strength polymer cementitious composites made from blast furnace slag (an industrial by-product). And we were used the activator which is necessary to function as a catalyst to induce the hydration of blast furnace slag. In addition, we were used the polypropylene fibre, and porcelain to improve the fire-resistance. To evaluate the properties of eco-friendly fireproof high-strength polymer cementitious composites, we tested mechanical properties in laboratory experiments such as compressive strength and fire-resistance. The tested composite performed just as well as conventional fireproof cement material, and notably had high residual strength.

► Cementitious fireproof material is widely used to protect concrete structures against fire.
► Eco-friendly fireproof high-strength polymer cementitious composites were developed.
► The mixture contains 0.1% polypropylene fibre, 15% porcelain, and 100% blast furnace slag.
