This article is focused on lightweight aggregate-concrete modified by municipal sewage sludge and lightweight aggregate-concrete obtained from light aggregates. The article presents laboratory examinations of material physical parameters. Water absorptivity of the examined material was decreased by the admixture of water emulsion of reactive polysiloxanes. Water transport properties were determ...

LIGHTWEIGHT CONCRETE May consist of lightweight aggregates are used in ordinary concrete of coarse aggregate and sand, clay, foamed slag, clinker, crushed stone, aggregates of organic and inorganic. It used in different common shapes such as light weight aggregate concrete [1], concrete without fine [2] or concrete with bubble [3]. It is replaced by normal concrete in several applications becau...

This study investigated the effect crumb rubber recycled from wasted tires on properties of structural lightweight aggregate concrete (LWAC). Two types were tested: control LWAC and rubberized (RLWAC). The consisted cement, fine (river sand), coarse (porous aggregates). For RLWAC, was replaced by at rate 10, 20, 30, 40, 50% volume. water to cement ratio for both set 0.35. experiment series dens...

Lightweight concrete (LWC) is a kind of concrete that made of lightweight aggregates or gas bubbles. These aggregates could be natural or artificial, and expanded polystyrene (EPS) lightweight concrete is the most interesting lightweight concrete and has good mechanical properties. Bulk density of this kind of concrete is between 300-2000 kg/m3. In this paper flexural strength of EPS is modeled...
