Manufacturing Light Concrete with PET Aggregate

Dec 09, 2012 The manufacture of concrete using a polymer instead of a stony coarse aggregate known as gravel is presented. Polyethylene terephthalate (PET) is the polymer used, recycling soft drink containers with sufficient tenacity . PET is a material commonly used by engineers as a structural element, not as an aggregate. The research work revealed that PET aggregate produces good

The Effect of Coarse Aggregate on Fresh and Hardened

Abstract Self Compacting Concrete (SCC) is new type of concrete that posse's property of high flow ability, passing ability and stability. To achieve SCC, many factors must be investigated. Coarse aggregate is one of these factors that have a significant influence on SCC. This paper presents the coarse aggregate properties such as maximum size, texture and type of coarse aggregate that have

[PDF] Use of recycled concrete rubbles as coarse aggregate

The use of concrete in structures consumes millions of tons of aggregates. Since earth is the source of the aggregates (either natural or crushed), then obtaining these amounts would have an adverse effect on the environment. Furthermore, demolishing concrete structures and dumping the concrete rubbles would aggravate the problem. Therefore, it becomes necessary to recycle the crushed concrete

Reappraisal of Recycled Concrete Aggregate as Coarse

Jan 01, 2009 State departments of transportation began using recycled concrete aggregate (RCA) as aggregate in portland cement concrete pavement in the United States in the late 1970s. Although RCA is rarely used in current U.S. rigid pavement slabs, the impetus for its continued use remains the same: a lack of landfill space, a shortage of nearby quality
