Effect of Quartz sand Grains Diameter on the Mechanical Properties of Mortars IJTSRD
The aim of this study is to evaluate experimentally the influence of quartz dune sand incorporation in the cement matrix by mass substitution at different percentages and diameters, on the mechanical properties of the mortars. Properties of the mortars were determined by flexural traction and compressive strength the results obtained highlight the effect of the […]
An Experimental Study on Low-Calcium Flyash and Metakaolin Based Geo-Polymer Concrete IJTSRD
Geo-polymer concrete is known as one of environmental- friendly construction materials. Using by-product material such as flyash and metakaolin replace cement would avoid carbon dioxide CO2 emission during the manufacturing process of ordinary Portland cement OPC . The objective of his research work was to produce a carbon dioxide emission free cementious material. This paper […]
Behaviour of Interlocking Hollow Concrete Blocks IJTSRD
India is one of the highly populated countries of the world. It ranks the second in population next to China. Besides this, major section of the people live below poverty line. Due to over population, poverty, high land value & house deficit, major cities like Delhi & Mumbai are covered by slums. These slums not […]
Evaluation of Dispersion Potential for Some Problem Soils in Central Myanmar IJTSRD
Dispersive soils which occur in central region of Myanmar are easily erodible and serious problem of stability of embankments, earth dams, earths and earth retaining structures. These soils are found in regions where the annual rainfall is less than 800 mm. Dispersive soil is structurally unstable and the presence of dispersive soil is indicated by […]
The Comparative Study on Improvement of Tender Systems in Myanmar IJTSRD
The purpose of this paper is to improve the different types of only public tender systems and contract systems in Myanmar. The study is divided into two parts. The first one is comparing the tender systems and the second is comparing the contract systems. Firstly, tender systems of each ministry are studied. When studying the […]
