Liquid Paraffin wax as a curing agent in SCC by using slag as aggregate

Abstract

There are hot climates in many places of the world. In hot, dry areas, the typical summer temperature ranges from 40- 50°C, with direct sunlight temperatures above these values. Concrete curing may be challenging in some places due to a lack of adequate curing water and rapid water loss due to evaporation. The current study analyses the effect of natural coarse aggregates (granite), known as Ferro silica slag aggregates, on concrete is workable and mechanical properties (FSS). Self-curing mixtures as a substitute for water curing were advised for many years. However, few types of research on their performance were carried out in hot weather, i.e., midday temperatures. During this study, the impact of a hot climate can be obtained by curing chemical substances to the fresh and mechanical properties of self-curing (SC) concrete and standard water cured concrete(W). Light Paraffin Wax, known as light molecular weight wax(LMW), and Heavy paraffin wax, known as  Heavy molecular weight wax(HMW), can be a perfect substitute to increase SCC performance. Internally, these self-cure admixtures the concrete useful for CSH gel formation. The result of utilizing paraffin wax in SCC as a self-curing component is examined in this research. A comparison considers three conditions of curing: wet curing, self-curing, and internal curing (I). The above two cure agents have been used to test various doses, i.e., 0 %, 0.1 %, 0.5%, and 1.0 % of paraffin wax weight. Tests have determined the self-curing admixture is performance: fresh, hardened, and Modulus of elasticity(MOE). This work reveals that steel slag is as coarse aggregate and paraffin as curing agents in the SCC are potential sustainable material concrete.
