Self Compacting Concrete: In special occations where it is difficult to do the compaction of concrete manually, the self compacting concrete is used. Self comapaction of the concrete is achieved through the mix design. Deep and large foundations, concreting of piling, etc are done with the self compacting concrete.

amount of concrete surrounding the reinforcing bar increased. Foroughi et al. (2022) investigated the bond strength of the reinforcement steel bars in self-compacting concrete. They concluded that the self-compacting concrete specimens generated higher bond to reinforcing bars than the normal concrete specimens and the correlation between bond
30-09-2022 · Methods of Self-healing in Concrete. There are various types of self-healing methods of concrete. Some of them are : Autogenous Self-healing Concrete. Concrete in itself processes naturally certain autogenous healing properties. In this method unhydrated cement particles work as a healing material.
moduli are feasible to reach and expect. Pumping concrete to high levels sets demands on the concretes flowability and self-compacting concrete is necessary to use. Ways of improving the concrete properties are also studied. All studies show that the Tubed Mega Frame structural system would be possible to construct with today's concrete and
The type of test ingredients used for obtaining self-compacting high-performance concrete (HPSCC) has been carefully selected to be universal. For this purpose, an extensive statistical analysis of the obtained results of the literature research was carried out. Then, universal and adapted to the typical range, highly fit statistical models are presented that can support the …
