Self-compacting concrete (SCC) is a new concrete technology developed during last two decades and it has become very popular in the construction industry. Filling ability, Passing ability and Resistance against segregation & bleeding, are the main properties of Self-compacting concrete. The main problem in designing of SCC is the selection of appropriate ingredients. All super plasticizers and viscosity modifying admixtures (VMA) are not compatible with any kind of cement. An experimental investigation has been undertaken to produce Self-compacting mortar and Self-compacting concrete to...

Fly ash based geopolymeric binders have potential for a wide range of high temperature applications and it is receiving more attention due to their economic and environmental advantages. This kind of Geopolymeric materials possess intrinsic fire resistance due to their rigid 3-D aluminosilicate structure. Geopolymer specimens remains dimensionally stable at high temperature and provides good compressive strength also. The percentage of Na2O and SiO2/Na2O ratio affect development of internal pore structure of Geopolymers and subsequently its performance at elevated temperature. The...

Geopolymers are currently attracting widespread attention due to their potential utilization as high performance, environmental friendly and sustainable alternative to Portland cement. The present research reports the manufacturing process and engineering properties of low calcium fly ash based geopolymer composites. Initially, the effect of geopolymer synthesizing parameters such as alkali content, silicate content, water content, sand content,curing temperature and duration of thermal curing on compressive strength have been presented for certain level of understanding regarding geopolymer...
