Comparative relevant aspects regarding lightweight concrete containing polystyrene beads
Abstract
Generally, the main of this experimental work is to found new resources in materials of constructions, especially with the interdiction of the exploitation of some sea sand careers. Thus, advanced constructors use light products, which is going to represent a primordial advantage in the reduction of the seismic risks, because the seismic strength represents a fraction of the total mass of the construction. Moreover, the use of lightweight materials and concrete gives a prime advantage in Algeria regarding the earthquake so try to lighten the slabs as much as possible. Lightweight aggregate concrete is characterized by a combination of cement and low-hardness aggregate. These aggregates have the characteristics of high porosity; they can absorb a large proportion of water from fresh concrete, which reflects the water demand of lightweight aggregate. The latter is also seriously affected by the surface structure and shape of the aggregates used. Based on fly ash aggregate and polystyrene concrete, this paper studies the preparation of lightweight concrete with different amounts of polystyrene concrete instead of fly ash sand. The results show that the cement quality and aggregate density affect the workability and lightweight of concrete.
