Determinação da influência de dois fatores na resistência do Cimento Portland de alta resistência inicial (CPV-ARI).

Abstract

In Brazil, the cement market is considered one of the most competitive in the world, with several companies operating in the sector, such as Votorantim Cimentos, Cimento Nacional, CSN Cimentos, among others. In order to stand out in the market, industries are increasingly seeking ways to improve the quality of cement. Part of this pursuit involves determining parameters that influence the 28-day strength of the cement. In the cement industry, various parameters are analyzed on a daily basis, including Blaine and the percentage of fire loss. In order to understand the effects of these parameters on strength, some planning techniques can be used, such as factorial planning, recommended for studying the effects of two or more influencing variables. The results show that Blaine and the percentage of fire loss are extremely important factors in the variation of compressive strength at 28 days.
