Recently, the demolition of old houses and the construction of new buildings in Kathmandu valley are in the peak which in turn generates a huge amount of construction waste. This construction waste is rich source of alumino-silicate and thus used as raw material for the synthesis of geopolymer in this study. Geopolymers have been synthesized from construction waste using NaOH and Na2SiO3 as act...

In this research, marine clays has been studied its potential as a matrix composite materials that tend to be used as alternative materials to concrete. The study shows that marine clays which mixed with appropriate proportion of alkaline activator could have strength requirements for masonry cement. The alkaline activator that been used for the geopolymerisation reaction is sodium silicate and...

The focus of the study was to identify stress strain behavior geo polymer concrete and salient parameters that influence mixture proportions properties low calcium fly ash- based polymers concrete. To develop geopolymer chemical are alkaline liquid solution/fly-ash ratio=0.5, Sodium silicate/sodium hydroxide ratio=2.5,16M NaOH SiO 2 /Na O ratio=2.0. mixes have shown improved values for same lev...

Geopolymers are inorganic aluminosilicate materials, which have been a great research interest as material for sustainable development. However, they possess relatively low toughness properties similar to brittle solids. The limitation may be altered by fiber reinforcement improve their strength and toughness. This describes the synthesis of bamboo shaving (BS) reinforced geopolymer composites ...
