Organic fireproof plugging material (OFPM) is widely used to plug the holes of substation cables passing through the wall, and fireproof performance of OFPM plays a vital role in fire safety. In this paper, thermogravimetric experiments of OFPM in nitrogen atmosphere at different heating rates were carried out to study the pyrolysis kinetics for …

Using pozzolanic materials in concrete manufacturing is intended as an optimal solution to lower the rate of greenhouse gas emission, and diminish energy resources and cement consumption. This study investigates the effect of using Semnan bentonite and kaolin as partial replacement for cement in low-strength concretes. A …

Kaolin Clay, an economical alternative to nanofillers, is an innovative mineral employed as a concrete additive. Historically, this material was used primarily as a cement substitute in concrete, owing to its inherent cementing properties. This study explores the potential of using Kaolin Clay as a partial replacement for ordinary Portland …

What helps concrete strive the fire-resistant properties is the precise composition of its mixture. Fireproof concrete has several residential and industrial applications. Commercially it is made with Portland cement and fly ash. However, you can also make fireproof concrete with just a few materials available at any home improvement store.
