A Study on Coefficient of Thermal Expansion of Geopolymer Mortars
Conventional Cement Concrete (CCC) consists of Portland Cement (P-C) as binder which binds the inert aggregate system. However, geopolymer composites (GPCs) have geopolymeric (GP) material
Influence of Curing Types on Strength of Geopolymer Concrete
In order to address environmental effects associated with Portland cement, there is need to develop alternative binders to make concrete. An effort in this regard is the development of geopolymer
Mechanical Water Dozer for Durable Concrete Making
Concrete is a porous material. This is the intrinsic property of concrete. Once the pores within structure of concrete are interconnected, this leads to creation of pathways (i.e. capillary porosity) for
Design of Buildings of Steel and Concrete
Public buildings requiring large floor area can be economically constructed adopting steel framework of columns, girders and flooring of reinforced concrete. The recently published steel code (IS:800-2007) includes Load and Resistance Factor methods of design adopted from the latest foreign codes. The outdated clauses for design of composite beams
Production of Self–compacting Concrete
For many decades, concrete has largely been used as a construction material, whether in moderate aggressive environment, or in strong aggressive environment. By volume alone, concrete is the world
Effect of Rice Husk Ash on Cement Mortar and Concrete
Workability, strength, and durability are three basics properties of concrete. Amount of useful internal work necessary to overcome the internal friction to produce full compaction is termed
