concrete pattern making. Introduction Precasting concrete is the process of making a concrete object using a reusable mold, typically constructed with handmade wooden forms. This is in contrast to the traditional concrete process that involves pouring concrete into a custom, single-use mold on site. In the precast
Concrete is the most important engineering material in construction industry because of its inherent strength properties. However, the addition of some other materials may change the properties of concrete. With increase in trend towards the wider use of concrete for pre-stressed concrete and high rise buildings there is a growing demand of concrete with …

OPC cements can be modified by using a range of additives. These may be defined as additives (at a level of ~5%), such as gypsum, which acts to retard hydration; replacements (at high levels up to 90%) such as BFS or PFA in blended or composite cements; or as admixtures (at levels of ~1%) such as superplasticisers. The main cement modifiers …
