The current study focuses on the utilization of Marble Waste Powder (MWP) as a partial substitution cement along with local sand instead microsilica in Engineered Cementitious Composite (ECC). aim was to reduce environmental concerns ECC by reducing content without adversely affecting desired properties. Four mixes were evaluated; control mix which has no MWP and three test having replacement 1...

Different mineral admixtures of Indian metakaolin, Iranian silica fume and nanosilica were used to produce high performance mortars. Two different sands types with grain size of 0.015-4mm were mixed with type II Portland cement, polycarboxylate superplasticizer,mineral admixture with 650kg/m3 cement content and water/cement ratio of 0.35. Different amount of cement was replaced by metakaolin or...

At present, the load-bearing enclosing structures of buildings and are designed built considering increasing requirements for energy efficiency saving such structures. This is due to need a thrifty attitude consumed strive greening construction increase In this regard, one most effective proven building materials cellular concrete. The purpose study was influence some prescription factors on st...

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...

One-part geopolymers were synthesized from two different silica materials (a silica-rich residue from chlorosilane production and a commercial microsilica) and sodium aluminate at three different SiO2/Al2O3 ratios and a nominal water/solids ratio of 0.5. The degree of reaction of the silica in the cured geopolymers (i.e. the fraction of silica dissolved to form aluminosilicates and minor produc...
