Demand for natural sand in concrete is increasing day by day since the available sand cannot meet the rising demand of construction sector. This paper reports the experimental study undertaken to investigate the influence of partial replacement of cement with Ground Granulated Blast Furnace Slag(GGBFS) in concrete containing quarry dust as fine aggregate. The cement was replaced by 10%, 20%, 30%, 40% and 50% of GGBFS and tests were conducted to determine the optimum level of replacement of GGBFS in quarry dust concrete. The specimens were subjected to compressive strength, split tensile strength, flexural strength, and bond strength tests at 7days, 28days, 56days, 90days and 150 days. The resistance to corrosion is evaluated based on the performance of the concrete for the penetration of chloride ions by means of impressed voltage technique in saline medium and Gravimetric weight loss method. Results herein reveal that an increase in slag proportion increases the strength properties and decreases the rate and amount of corrosion of reinforcement and among the various percentages of replacement 40% is found to be optimum with better strength and corrosion resistance properties.

Concrete plays important role in the construction of structures. The need for concrete increases day by day. Material required for concrete are getting depleted, so there is a requirement to find alternatives. At the same time the alternative materials should posses the property of the actual materials used in concrete and also they must provide the required strength to the concrete. Normally Concrete is firm in compression but anemic in tension and shear. The purpose of this study is to find the behaviour of concrete reinforced with hybrid macro fibers. By adding Glass fibers in percentages like 0.2%, 0.4%, 0.6%& 0.8% to the concrete, the properties like compressive, flexural and split tensile strength are investigated. The optimum percentage of glass fiber was found to be 0.4%. Quarry dust has been widely used in structures since ancient times. The present study is aimed at utilizing waste Quarry dust (WQD) in construction industry itself as fine aggregate in concrete, replacing natural sand and also by adding the optimum percentage of glass fibers. The replacement is done partially and fully in the various proportions like 0%, 25%, 50%, 75% and 100% and its effect on properties of concrete were investigated. The optimum percentage of the concrete by adding 0.4% of glass fiber and the proportions was found to be 25%.

Natural river sand is one of the important constituent materials in concrete production while stone dust is a material obtained from crusher plants which is also sometimes being used either partially or fully in replacement of natural river sand in concrete production. Use of stone dust in concrete not only improves the quality of concrete but also conserve the natural river sand. However, due its scarcity and environmental degradation caused resulting from excessive mining of Natural river sand, there is need to investigate an alternative material of the same quality which can replace river sand in concrete production. In the present study, experiments were carried out to study the gradation of aggregates, workability, compressive strength and split tensile strength of concrete made using quarry dust as replacement of fine aggregate at 0, 25, 50, 75, and 100%. Grade M15 of concrete was produced with ordinary Portland cement (OPC) for referral concrete while M25 of concrete was prepared for compressive strength and split tensile strength concrete. Workability and Compressive strength were determined at different replacement level of fine aggregate and optimum replacement level was determined based on compressive strength. Results showed that by replacing 50% of fine aggregate with quarry dust, concrete of maximum compressive strength can be produced as compared to all other replacement levels. The effect of quarry dust on compressive strength and split tensile strength was investigated and from the overall result obtained, it was observed that the compressive strength and split tensile strength increased significantly for all the curing ages from 0% to 50% replacement level of quarry dust. Maximum value obtained for 28day compressive and tensile strength were 25N/mm2 and 2.3N/mm2 respectively and this occurred at 50% replacement.

The production of Portland cement, the principal binder in concrete, is a major contributor for 6-8% of human generated green house gases that are involved in global warming and climate change. But when flyash, which is the residue from coal-fired power plants is used as partial replacement of cement in concrete, results in the reduction of environmental load and concrete production cost besides enhancing strength and protection of embedded steel in concrete from corrosive agents. This paper investigates the influence of 30% replacement of cement by flyash on the strength and corrosion resistive properties of concrete along with Triethanolamine as corrosion inhibiting admixture at the dosage of 1%, 2%, 3% and 4% by weight of cement. The specimens were tested for compressive strength, split tensile strength, flexural strength and bond strength. The resistance to corrosion is evaluated based on the performance of the concrete for the penetration of chloride ions by means of impressed current technique, half cell potential measurement and weight loss method. From the results obtained, it is found that flyash blended cement concrete increases the strength, reduces the permeability by the pozzolonic reaction, offers very good resistance against chemical attack and increases corrosion resistance with the addition of inhibitors.
