Comparative Study on the Behavior of Crushed and Rolled Sustainable Concrete Materials Based on New Generation of Superplasticizer at Curing Temperature

Abstract

The aggregates factory consumes a big quantity of energy; by consequence, it costs money, in the other hand it produces a lot of waste material or SCM (sustainable concrete material). The main aspects which guide this study is the current tendency to make mortar based on a very abundant material which are crushed limestone aggregates and naturals dunes sand. The results obtained in this study summarize up the importance of SCMs aggregates on behavior of the mortar, this different kind of SCM aggregate offered different behavior at the fresh state of the batch and by consequence its result with different mechanical behavior at the hardened state of mortar. This study focus also on the behavior of the new kind of chemical admixture, which is acrylic superplasticizer. The principal aim of adding rolled or crushed SCM is makes a mortar, which can resist to exhaustive environment (at curing temperature).
