Strength Properties of Concrete Containing Coconut Shell

PDF International Journal of Scientific & Technology Research

Specimens containing 5, 15, 25, 35 and 45% POFA were prepared at constant water-cement ratios of 0.5 with superplasticizer content of 0.5% with cement. Workability in terms of slump and strength properties were studied, and compared with control specimen.

Durability - Portland Cement Association

Durability is the ability to last a long time without significant deterioration. A durable material helps the environment by conserving resources and reducing wastes and the environmental impacts of repair and replacement. The production of replacement building materials depletes natural resources and can produce air and water pollution.

Hollow Concrete Blocks: All You Need to Know

08. As the hollow concrete blocks are light in weight, they reduce the weight of the structure and hence light structural member or less percentage of steel is required for a given R.C.C building. 09. Presence of rough texture on concrete blocks provides good bonding between cement mortar and concrete blocks. 10.

Physical and Mechanical Properties of Concrete with

This paper centers around the study of physical and mechanical properties of concrete reinforced with coconut fibre and the coarse aggregates of which are partially replaced with coconut shells. American Concrete Institute (ACI) method has been used to design M20 concrete wherein coconut shells (CS) replaced the coarse aggregates (CA) by 6%, 8%, 10%, 12% and 14% by volume.

Study on coconut shell concrete hollow blocks and the

Abstract In this study hollow blocks were produced using coconut shell (CS) as coarse aggregate. For comparison, hollow blocks were also produced with conventional concrete (CC). Mixes were produced both in field and laboratory. Both conventional and CS mixes satisfied the minimum strength required as per IS 2185 (Part 1): 1987. Hollow blocks were tested for their basic properties, shrinkage

The Differences Between Cement, Concrete, and Mortar

The Spruce / Liz Moskowitz. Concrete . Concrete is a complete building material used for foundation walls, concrete slabs, patios, and many other masonry structures. It is uniquely versatile because it starts out as a simple, dry mixture, then becomes a flexible, semi-liquid material capable of forming into any mold or shape, and which dries into the hard-as-rock material we know as concrete.

SAFE Features | ANALYSIS AND DESIGN OF FLOOR SYSTEMS

SAFE is ideal for modeling foundations, basemats, and footings. Easily model soil supports and zero tension soil models with uplift analysis. The area assignment of soil supports is based on the subgrade modulus, and they automatically adjust whenever the mesh changes. Basemat foundation models can include pedestals, walls, columns, beams, and
