Abstract Reactive powder concrete (RPC) is a special type of with remarkable properties, particularly compressive strength. Some its main disadvantages include high cement and SF content, fine quartz preferred size 150 ?m - 600 ?m, low water-to- binder ratio. These characteristics increase the cost RPC production affect sustainable development. Because this, researchers have resorted to explori...

Sulphate-induced heaving in soils is a common problem caused mostly by the use of calcium-based binders stabilisation sulphate-bearing soils. attributed to precipitation and growth ettringite minerals high alkaline environment. A sustainable means reducing sulphate-induced addition an additive called “RoadCem” (RC) stabilised cementitious products has not been studied. RoadCem that manufactured...

The evaluation of thermal properties is commonly conducted to characterize non-structural materials, such as lightweight concrete, that are used for insulation. Such materials designed resistivity applications. Due the increased demand adopt sustainable practices in construction industry, municipalities United Arab Emirates (UAE) emphasize use construction, green concrete. cement concrete parti...

Concrete is the most commonly used construction material because of its various advantages, such as versatility, familiarity, strength, and durability, it will continue to be in demand far into future. However, with today’s sensitivity environmental protection, this faces unprecedented challenges high greenhouse gas emissions, mainly during cement production. This paper investigates one promisi...

Abstract In recent years the word sustainability has become a priority of many researchers. this regard, evolutions were put forth in concrete industry one them is Geopolymer concrete. Ground granulated blast furnace slag (GGBS) used as source material which rich alumina and silica contents, forms silicate gel when mixed with an alkali solution sodium hydroxide then binds aggregate. Till now re...

In the recent past, importance of geopolymer concrete as an eco-friendly product to replace portland cement is continuously increasing over time. Yet less research effort has been invested in this area compared with some topical issues civil engineering. Thus, objective article analyse mechanical properties where replaced by fly ash and ground granulated blast-furnace slag (GGBS). Sodium silica...
