Concrete is a vital material and plays a major role in the quality of buildings or structures. One may say that the making of concrete is easy but it's not enough. It is important that a concrete mix is correctly designed, batched, mixed and transported, but it is also important to place concrete correctly. The placing of concrete is an

Abstract. Self-curing concrete is achieved by means of replacing a part of aggregate by lightweight aggregate or adding chemical admixtures. The self-curing process of concrete takes place from inside to outside, thus reducing the autogenous shrinkage and self-desiccation, especially for the high-performance concrete with relatively low water/binder ratio.

01.04.2017· So the structure made with the flexible concrete are more earthquake resistance. Self-healing property : The normal concrete has very low self-healing property as it has very low free cement concrete. The flexible concrete has a very good self-healing property as it can heal the micro-cracks itself by the reaction of carbon dioxide and water.

Li's self-healing concrete would cost about three times more than the standard item, he says, but pay for itself in reduced repair work. He estimates that the Grove Street Bridge, which crosses highway I-94 in Ypsilanti, Mich. and was built with traditional concrete, will average $350,000 a year in maintenance, user and environmental costs–its so called "life-cycle cost"–over 60

IMPORTANCE OF SELF. HEALING CONCRETE WHY THE NEED? Concrete can withstand compressive forces very well but not tensile forces. When it is subjected to tension it starts to crack, which is why it is reinforced with steel; to withstand the tensile forces DEFINITION Concrete which heals itself when it comes in contact with air and water,it produces lime on outer layer of concrete.
