Abstract: In developing countries where concrete is widely used, the high and steadily increasing cost of concrete has made construction very expensive. The production of concrete requires various materials like Cement, Fine aggregate and Coarse Aggregate .Due to extensively use of concrete which lead to an increase in cost of materials. Therefore an alternate material is used for partial replacement of Fine aggregate and coarse aggregate in concrete. This project is experimented to reduce the cost of concrete. In this research work experiments have been conducted with collection of materials required and the data required for mix design are obtained by sieve analysis and specific gravity test. Sieve analysis is carried out from various fine aggregates (FA) and coarse aggregates............

Abstract: The present work, advances in the characterization of the macadamia nut are shown. The study started from the fact that the diffusion in the cultivation and processing of macadamia nut inside the country is not fully developed; On the other hand, its exploitation can be technified through a sustainable use and of low environmental impact. The objective of this research is to propose alternatives of integral use of this fruit. The methodology used included physicochemical and instrumental analysis (infrared spectroscopy). In the case of oil, the peroxide, saponification and acidity indices were obtained...........

Abstract: This paper presents, stress analysis of a ladder type cross over electric car chassis structure using FEM. The commercial finite element package SOLIDWORK was used for the solution of the problem. Two type of chassis was analysed, solid plate beam and porforated plate beam chassis. To reduce the weight of the chassis of the cross over electric car, the chassis structure design was modified by porforating the beam so that the main beam is not solid. The boundary conditions applied to this model of chassis can be classified into four general cases: static condition., the car climb 30o..........

Abstract: The development of Self-Compacting Concrete (SCC) has recently been one of the most important developments in the building industry. The paper investigates the influence of aggregate sizes of 10mm, 12.5mm and 20mm on the performance indices of Self-Compacting Concrete (SCC). Concrete mixes of 1:2:4 were produced with addition of variable plasticizer admixture of COMPLASTSP430 at 3% constant value. Specified tests for Self-compacting concrete (SCC), related to workability such as flowability, filling-ability, and passing-ability tests were carried out on fresh samples. Compressive strength of hardened cured (150 x 150 x 150), results showed a maximum compressive strength of 19.86N...........
