Feasibility Study on Lightweight Aggregates in Concrete A Review
studies on waste materials as construction materials. KEYWORDS: Palm kernel shell ash, pozzolan, concrete and compressive strength 1. INTRODUCTION The utilisation of supplementary cementing materials such as fly ash, slag and silica fumes has proven effective in making strong and durable concrete and to provide solution to the
The present experimental work deals with the study of mechanical and flexural properties of coconut shell ash reinforced epoxy composites. Carbonisation method was used to prepare the coconut shell ash by heat treating the crushed coconut shell at a temperature of 600 and 800 degrees.
Abstract. Coconut Shell Powder were . obtained from coconut shell tha. t had been discarded and grinded until it become in a form of powder. This study were conducted to determine the chemical and physical properties of coconut shell powder to be used as a filler inside concrete.
A combination of Egg shell with silica fumes are used in different combinations to find the feasibility of using the Egg shells as an alternate to cement Egg shell powder replaces 10%, 20% and 30% in addition with the silica fume by 5%, 10%, 15% of weight of cement. Concrete is cast and Compressive test, Tensile and Flexural tests

Durability study of concrete structure in marine ...
Experimental Study on Properties of Concrete by ... Abstract— Concrete is today the largest consumable material in the world that utilizes the natural resources such as sand, crushed stone and water. Due to the depletion of these natural resources for concreting, research is ... silica fumes, egg shell, ceramic waste etc. Among
the controlled concrete specimens. In this project M30 Concrete is designed for various combinations. A combination of Egg shell with silica fumes are used in different combinations to find the feasibility of using the Egg shells as an alternate to cement Egg shell powder replaces 10%, 20% and 30% in addition with the silica fume by 5%, 10%, 15% of
conventional concrete and coconut shell concrete for improving the strength then ordinary concrete. In the increasing of silica fume in concrete the strength will be increasing with reduced aspect ratio. The silica fumes are added 0%, 2% up to 26%. Test for concrete; 1) Fresh concrete 2) Hardened concrete
made up of Calcium. A combination of Egg shell with silica fumes are used in different combinations to find the feasibility of using the Egg shells as an alternate to cement Egg shell powder replaces 10%, 20% and 30% in addition with the silica fume by 5%, 10%, 15% of weight of cement. Concrete is cast and Compressive test,
A comparative study on egg shell concrete with partial replacement of cement by fly ash. International Journal for Research in Applied Science and Engineering Technology vol. 3 Dixit M. Meena A. Malik A. Chhinderpal and Sundesha K. 2016. Effect of using egg shell powder and micro silica partially in place of cement in M25 concrete.
varying proportions of coconut shells. The rice husk ash and silica fume were used to develop two reference concrete mixtures. The results show that the properties of hardened concrete decrease at temperatures of more than 400 °C. Key words: lightweight selfcompacting concrete, coconut shells, rice husk ash, silica fume, high temperature
Therefore to form another track for research on coconut shell concrete, already a study was taken and produces a kind of coconut shell concrete pipe [27] and hence in this study, an attempt is made to produce manhole cover slabs using coconut shell as a coarse aggregate and studied the essential properties and reported.
Feb 05, 2019· The water absorbed by the coconut shell during the course of soaking is stored and the pore structure in the coconut shell behaves like a reservoir. Intermittent curing condition produces the highest coconut shell aggregate concrete strength followed by full water curing . Coconut shell concretehave a good quality in itslater stage.
Feb 22, 2016· • To study the properties of coconut shells, compatibility of coconut shells with cement and to produce coconut shell aggregate concrete with 28 day compressive strength more than 20 N/mm2. • To study the strength properties of concrete in replacement of coarse aggregate .
and 42% for concrete produced from coconut shell and palm kernel shell respectively [6,7]. Siti Amin Bt Tukiman and Sabarudin Bin Mohd (2009) replaced the coarse aggregate by coconut shell and grained palm kernel in their study. Percentage of replacement by coconut shell were 0%, 25%, 50%, 75% and respectively.
Aim of the research was to investigate the effect of Coconut Shell Ash (CSA) with cement as a partial substitution in the production of alternative cement blocks to subsist conventional ones. Utilization of this natural agro waste material helps to prevent the environmental pollution, reduces the construction cost as well as contributes to sustainable construction.
