Use of Recycled Aggregates in Concrete to Achieve Characteristic Strength M50 with Addition to Steel Fibre
Abstract: Concrete is World’s second most consumed material after water, use of recycled aggregate (RA) in concrete can be useful for environmental protection. Recycled aggregates are the materials for the future. Aggregate is one of the main ingredients in producing concrete. It covers 75% of the total for any concrete mix. The strength of the concrete depends on the properties of aggregates used. The experimental analysis comprise with normal RAC and …

EXPERIMENTAL INVESTIGATION ON GEOPOLYMER CONCRETE
Abstract: The project report entitled “Experimental investigation on alkali activated concrete” describes the detailed experimental work carried out on Alkali Activated Alumina-silicate concrete [Provis and Deventer, 2009]. The fly ash- Ground Granulated Blast Furnace Slag (GGBFS) based Alkali Activated Alumina-silicate concrete cured at ambient temperature was prepared by using different molarities of Alkali Activated solution namely 8M, 12M and 16M. The properties of concrete such as workability, compressive strength, Pull-out test/bond …

INVESTIGATION OF STEEL FIBER REINFORCED CONCRETE CORBELS BY EXPERIMENTAL AND ANALYTICAL METHOD
Abstract: In the present paper, an experimental results and predicted values by truss analogy method, ACI Building Code (ACI 381-83) provisions for corbels, and method given by Fattuhi is investigated. The concrete used in the corbels is of M-60 grade. Test were carried out on 27 samples of size 150 x 150 x 200- mm were shear span was varied from 175 to 200 as shown in table (5) and concrete …

Effect of Replacing Rice Husk Ash with Cement and Granulated Blast Furnace Slag with Fine Aggregates on High Performance Concrete
Abstract: Cement and sand are the basic materials for any concrete construction. Now a day’s due to erosion of rivers and considering environmental issues, there is a scarcity of river sand. Many researchers are finding different materials to replace sand and one of the major materials considered in this study is granulated blast furnace slag (GBFS). In recent times, instead of cement many alternative materials are being used as the binding …

Effect of variation of Elevated Temperature on Compressive Strength of Metakolin concrete
Abstract: It has been found that high early temperature has negative impacts on later compressive strength of concrete. Some researchers investigated the adverse effect on long term strength of concrete due to high initial temperature. The effect of temperature on different properties of concrete is considerable and remained the subject of research activities of a lot of researchers. Different investigators moved in different ways and investigated temperature effect by changing different …
