Study of Non Sintered Cement Mortar Using Nanoslag and Alkali Activator

Abstract

As global warming has had harmful effects on the environment, the construction industry has made efforts to reduce the amount of CO 2 generated in the process of cement production. There is an urgent need for an alternative material that can replace cement. To improve the initial strength and economical efficiency pointed out as problems, this research was conducted for Blast Furnace Slag (BFS), an industrial byproduct. Non-sintering cement (NSC) was used by minimizing the amount of high-priced alkali activators. By using Nano-technology, fineness has been maximized, to enhance the initial strength of BFS. This research is based on non-sintered cement replaced by nano-slag using alkali activators, and the fundamental properties and quality of the non-sintered cement were investigated. A variety of activators were used, up to 10 percent of the slag weight. This research aims to present fundamental data through a comparative analysis of flexural strength, compressive strength, time of setting, diabetic temperature, and rising heat.

Evaluation of the Performance of the PVA Fiber Reinforced Inorganic Binder and Industrial By-products Building Board

“…In fact, cement production creates about 7-8% of the world's greenhouse gases [1,2]. In addition, the construction materials made of cement as a main ingredient have been highlighted as a problem because they include heavy metals and hazardous materials including Pb, Cd, Cr The aim of this research is to produce a building board, a secondary product, by replacing cement with industrial by-products: blast furnace slag (BFS), red mud (RM), and silica fume (SF), and to assess the characteristics of the board with reinforced bending strength by mixing PVA fiber to the optimal mix proportion of inorganic binder [3,4,5]. Figure 2 is a flow chart that shows the process of the study.…”
