Abstract

Geopolymer concrete prepared from low lime based fly-ash and a mixed alkali activator of sodium hydroxide and sodium silicate solution are investigated. An increase in compressive strength of these concrete samples is observed with increased molarity of NaOH solution. The workability of concrete decreases when the molarity of NaOH solution is increased for the samples cured at 60°C.

Abstract

It is expected that in the near future, the civil engineering community will have to produce structures in harmony with the concept of sustainable development through the use of high-performance materials with low environmental impact that are produced at a reasonable cost. Magnetic water concrete, synthesized from the normal materials used for manufacturing of concrete, provides one route towards this objective. This paper presents the effect of addition of magnetic water on workability, strength and mechanical properties of concrete tested show-encouraging results, and one can easily replace normal water with magnetic water by which quantity of cement used in any concrete mix reduces and can be made as new Eco-friendly construction material for future decades.
