Abstract
Eksperimentalno istraživanje čvrstoće laganog geopolimernog betona s dodatkom ekološki prihvatljivih materijala
Highlights
An increasing demand for concrete in construction industry that uses conventional aggregates has greatly reduced the natural stone deposits, which is why there is a pressing need to discover a suitable replacement material as a substitute to natural stone [1, 2]
Mix design is the process of selecting appropriate percentage of cement(C), fine aggregate (FA) and lightweight coconut shell coarse aggregates (LWCSA) and water to produce concrete of sufficient strength
It should be noted that all LWCSA were used with high cement content and lesser amount of aggregate since the strength of the concrete is influenced by aggregate which can be used for structural applications
Summary
An increasing demand for concrete in construction industry that uses conventional aggregates has greatly reduced the natural stone deposits, which is why there is a pressing need to discover a suitable replacement material as a substitute to natural stone [1, 2]. Adopting the waste management process involves the utilization of waste by–products, which reduces the environmental impact to a considerable extent One of such by-products is the ground granulated blast furnace slag. According to ASTM C330/C330M- 14 [15], aggregate is defined as lightweight when its bulk density is less than 880kg/m3 for coarse lightweight aggregate, and less than 1120kg/m3 for fine lightweight aggregate [16]. an attempt was made to produce a GGBS based geopolymer lightweight coconut shell concrete It produces inorganic polymer composites which have the potential of forming a substantial component of an environmentally sustainable construction exhibiting the strength equivalent to the strength of an ordinary conventional concrete. Experimental investigations were carried out to find out the compressive strength, stress-strain behaviour, and modulus of elasticity
