Haiti is not alone amongst developing nations that have suffered losses due to the poor construction of concrete and masonry structures in an earthquake. In the wake of the disaster, a considerable amount of public sympathy and substantial funding was raised that supported short term, front line activities. However, there is little recognition of the need for adequately funded systems of organi...

The durability of concrete different internal structures is different. We can use small water-binder ratio and add admixture to improve the tightness reduce defects. For achieve purpose improving durability, strictly control from raw materials, mixing, transportation, pouring, maintenance other process.

Abstract Suitable distribution of particles and the presence hydration lead to improved compressive performance optimum (even reduced) cost in production reactive powder concrete (RPC). This study was conducted obtain a better understanding RPC analyze behavior modified (MRPC) using properties surface resistivity, water penetration, strength, modulus elasticity, apart from cost. The present car...

The aim of this study is to experimentally investigate the mechanical characteristics concrete combining silica fume (SF) and magnetized water (MW). A total nine mixes were prepared tested for workability, compressive strength, splitting tensile flexural strength. Ordinary tap (TW) MW that was with five proposed different methods utilized in mixes. by passing TW through a permanent magnetic fie...
