Marble Dust, Glass fiber, M30 Grade of Concrete, MgSO4, Sea Water, Compressive Strength Test, Durability Test
Abstract
The infrastructure needs of our country is increasing day by day and with concrete is a main constituent of construction material in a significant portion of this infra-structural system. It is necessary to enhance its characteristics by means of strength and durability. An experimental study proposing changes to the conventional concrete to increase fire resistance, increase crack resistance, increase ductility and flexural strength by partial replacement of Marble dust to the cement and Glass fiber in the preparation of the concrete for M30 grade of concrete.
Allowing the waste materials to the environment directly without proper treatment can cause environmental hazards. Hence as far as possible reuse or proper recycling of waste material has been emphasized. Waste can be used to produce new products or can be used as admixtures so that natural resource scan is used more efficiently and the environment is protected from waste deposits & other hazards. Fibres impart energy absorption, toughness and impact resistance properties to fibre reinforced concrete material and these characteristics in turn improve the fracture and fatigue properties of fibre reinforced concrete research in glass fibre reinforced concrete resulted in the development of an alkali resistance fibres high dispersion that improved long term durability. This system was named alkali resistance glass fibre reinforced concrete.
In the present study the marble dust and alkali resistance glass fibre with varying proportions 1%(GF),5%(MD) and 2%(GF),10%(MD) are mixed with concrete materials and hence an experimental investigation is carried out to study the effect of Glass fibre and Marble dust on compressive strength and durability of M-30 grade concrete.
