Studies on workability, microstructural and hardened strength properties on self-compacted geopolymer concrete subjected to ambient curing.

Due to the enormous increase in the development of infrastructure in a very short span, there is an urge in the need of cement that is commonly used as a binder in the construction industry. This research work carries out the formation of self-compacted geopolymer concrete with the help of alkali activators that are used for curing under ambient curing. Durability, mechanical properties and microstructural analysis of ten different types of mixes of concrete with different combinations of fly ash, micro fly ash and slag were studied in detail.

Gravimetric weight loss of steel in self-compacting concrete blended with wood ash and silica fume.

The present research work deals with the development of self-compacting concrete (SCC) containing wood ash (WA), silica fume (SF) and their combination (1:1 ratio). Several research studies have reported on the performance of WA and SF-blended SCC. However, very limited information is available on the effects of silica dioxide (SiO) and subsequent formation of calcium-silicate-hydrate (C-S-H) gel and its benefit on the strength and durability enhancement of self-compacting concrete.

Strength and durability characteristics of steel fiber-reinforced geopolymer concrete with addition of waste materials.

In general, all countries in the world use ordinary Portland cement concrete for the construction purpose; this ordinary Portland cement (OPC) gives good mechanical properties and durability to the buildings. The binder cement and the filler aggregate are the ingredients widely used in the process of concrete. Natural resources are used to extract both filler and binder elements.

Effect on mechanical properties of lightweight sustainable concrete with the use of waste coconut shell as replacement for coarse aggregate.

Concrete is one of the most important materials that are used in the construction industry all around the world. A larger part of the capacity in concrete is generally employed by the coarse aggregate. Due to the tremendous use of coarse aggregate in the construction industry, the material is getting degraded.
