Experimental Study On Strength And Workability Of Cement Materials Essay

EXPERIMENTAL INVESTIGATION ON WORKABILITY OF CONCRETE WITH PARTIAL REPLACEMENT OF CEMENT BY GROUND GRANULATED BLAST FURNACE AND SAND BY QUARRY DUST Yogesh Soni *nidhi gupta ** yogeshsoni616@gmail.com * *Research Scholar, Department of Civil Engineering, RKDF Institute of Science & Technology , Bhopal ** Asst .Prof ., Department of Civil Engineering, RKDF Institute of Science & Technology , Bhopal Abstract-Concrete is the most widely used construction material in civil engineering industry because

being built all over the world, but construction using the concrete always occupies the top place. In all these constructions, usage of cement is unavoidable as it is the soul of the concrete. But we all know that the cement production has to be reduced due to the emission of carbon dioxide during its manufacture. Hence fly ash can be partially replaced with the cement and can be effectively used for the construction. Fly ash is a finely divided residue resulting from the combustion of ground or powdered

UTILIZATION OF HYPO SLUDGE WASTE FROM PAPER INDUSTRY IN THE PRODUCTION OF CONCRETE A Project Study Presented to the Department of Civil Engineering and Environmental & Sanitary Engineering College of Engineering, Architecture, Fine Arts & Computing Sciences Batangas State University Batangas City In Partial Fulfilment of the Requirements for the Degree of Bachelor of Science in Civil Engineering By: Belegal, Adrian M.

The Strength of Concrete with Ordinary Portland cement’. The author has observed that the addition of micro silica in concrete reduces the capillary action, absorption and porosity because of fine particles of silica fume. It also decreases the voids in concrete (1). * Amar Devendra Shitole et al.., studied in ‘The Use of Micro-Silica to Improve the Compressive and Flexural Strength of Concrete’. The author has concluded that 7.5% replacement of cement by Microsilica can induce higher strength properties

demand for construction materials. Concrete is the most important construction material. Concrete is a mixture of various ingredients like aggregates, water and admixture. Aggregate form is the major part of concrete among the entire ingredients used in concrete. The use of normal weight of aggregate such as gravel and granite probably reduces the natural stone deposits and it cause effect on environment. Therefore, it is necessary to explore and to find out suitable material for the replacement and

possibly be one of the chief beneficiaries of these materials, because the properties of concrete, steel, glass and other building materials will improve with the applications of nanomaterials. Therefore, the potential use of nanomaterials such as carbon nanotubes, Cu nanoparticles, Ag nanoparticles, TiO2, SiO2, Al2O3, ZrO2, and Fe2O3 nano-oxides for enhancing the mechanical strengths and durability of concrete have been explored in the current study. It has been observed that the addition of nanomaterials

important available materials for construction in Egypt and all over the world. It is used in almost all structures as: buildings, shells, bridges, tunnels, tanks and retaining walls. Concrete is made by mixing binding materials as sand and gravel held together with a paste of cement and water. The used of admixture is to change certain characteristic of concrete such as workability, durability and time of hardening. Some of concrete advantages are its high compressive strength, its ability to cast

types of concrete. This study is part of a present research that leads to estimate the level of concrete degradation properties caused by high temperatures, mostly by using the concept of maturity. In order to evaluate the coupled effect of high temperature and heating time on the residual strength of concrete, a series of compressive and indirect tensile tests was performed on normal and high strength concretes. The effect of incorporating polypropylene fibers in high strength concretes was also investigated

Natural Sand which is used as a construction material is becoming scarce now-a-days and state governments are imposing restriction on unlimited excavation of Natural sand from river beds. This has made prices of Natural sand reach its peaks. Now there is every need for a suitable replacing material for Natural sand. An attempt is made in this context to replace natural sand by Granite fines by adopting M20 Grade concrete with a mix design of 1: 1.73: 3.1 of cement: Natural sand& Granite Powder : Gravel
