In present scenario concrete is highly consumed material in construction field due to its advantages, because of this the natural resources are depleting day by day at an alarming rate and there is an immediate need for finding alternate materials to the natural materials in concrete. In this paper an effort is made to find alternate partial replacement materials for cement and fine aggregate (FA). M40 grade concrete is adopted and the cement was replaced with egg shell powder with different percentages of 5%, 10% and 15%. The optimum percentage egg shell powder (ESP) is obtained at 10%. At optimum ESP the FA is replaced with Quarry Dust (QD) with percentages of 25%, 50%and75%. The maximum strength properties are obtained at 10% ESP and 50% QD and the concrete is also durable at 10% ESP and 50% QD with Water Cement Ratio is 0.38.

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.

As construction in India and other developing countries are increasing, the consumption of energy and resources are also increasing in same alarming way. Due to urbanization many industries are developed and the industrial wastage is also increasing day by day which is a serious concern to the environment. Many industries produce various end products, which may be used in construction industry at various places. So we focused on some of the waste materials which can be replaced in conventional concrete, and by then cost of construction can be reduced and is economical, also damage caused to the environment can also be reduced, at the same time landfills can also be reduced. So, we focused on reducing the virgin materials in concrete like cement, fine aggregate and coarse aggregate by replacing them with some waste materials which have same properties of cement, fine aggregate and coarse aggregate. The objective of the present work is to find out the effectiveness of fly ash, quarry dust and crumb rubber by replacing them in varied percentages. Here, cement is replaced by fly ash with percentages as 30%, 40%, 50%, 60% and quarry dust as fine aggregate with percentages of 20%, 30%, 40%, 50% along with crumb rubber as coarse aggregate with percentages as 5%, 10%, 15%, 20%. The results in this study have shown a gradual reduction of compressive strength as we kept on adding the crumbed rubber. Even though the strength obtained for 5% usage of crumbed rubber was quite satisfactory.

This paper reports the findings of the effect of elevated temperature on the compressive strength and durability properties of crumb rubber engineered cementitious composite (CR-ECC). The CR-ECC has been tested for its compressive strength and chemical resistance test against acid and sulphate attack. Different proportions of crumb rubber (CR) in partial replacement to the fine aggregate and polyvinyl alcohol (PVA) fiber have been utilized from 0 to 5% and 0 to 2%. The experiments were designed based on a central composite design (CCD) technique of response surface methodology (RSM). After 28 days curing, the samples were preconditioned and exposed to high temperatures of 100 °C, 200 °C, 300 °C, 400 °C, 500 °C, 600 °C, 700 °C, 800 °C, 900 °C, and 1000 °C for one hour. Although the residual compressive strength of CR-ECC was negatively affected by elevated temperature, no explosive spalling was noticed for all mixes, even at 1000 °C. Results indicated that CR-ECC experiences slight weight gain and a reduction in strength when exposed to the acidic environment. Due to the reduced permeability, CR-ECC experienced less effect when in sulphate environment. The response models were generated and validated by analysis of variance (ANOVA). The difference between adjusted R-squared and predicted R-squared values for each model was less than 0.2, and they possess at least a 95% level of confidence.

The aim of this research is to investigate hardened state properties of Self Compacting Concrete (SCC) containing low calcium based fly ash. The mixtures were prepared using various proportions of Class F fly ash ranging from 0% to 30% cement replacement. Water to powder ratio is 0.38 – 0.39 and powder content was kept constant at 540 kg/m3. Properties investigated were strength properties (compressive strength and splitting tensile strength), and durability properties (complete immersion water absorption, apparent volume of permeable voids (AVPV), sorptivity, and RCIPT tests. These tests were done at various days. Results showed that fly ash replacement of up to 30% gave acceptable strength and durability properties for medium strength SCC.

Glass waste & Egg Shell Powder cannot be processed for useful applications and may end up in a landfill. In India nearly 30 tonnes of Glass waste in every metropolitan city generated every year. This establishes the ecological problem and is measured an additional problem on the previouslyclose-fitting landfill space.This article studies the possibility of using post-consumer Glass Waste Powder and Egg Shell in Powder form as a fractional substitute for conservative cement on concrete. During manufacturing of cement it emits a huge carbon di oxide and cause various effect to atmosphere. In this project tried to minimize the usage of cement by partial replacement of waste material from general utilities. Here I replaced cement by partial as glass powder and egg shell powder with a percentage of 0 %, 20%, 30%, and 40% and for its compressive strength up to 7, 14 and 28 Ages evaluate the strength properties. Comparison result has obtained by cube test & split tensile test. Since now a day’s the developing and developed countries are facing lack of post consumer dumping site and it has become extremely serious difficulty. This waste product should convert resource of by-product to control environmental pollutions.
