This led to the development of self-compacting concrete, primarily through the work by Okamura. The first usable version of self-compacting concrete was completed in 1988 and was named “High Performance Concrete”, and later proposed as “Self Compacting High Performance Concrete”.
In Japan, the volume of SCC in construction has risen steadily over the years.
Maximum recommended volume of water is 3.15 L (0.83 US gallon) per 30 KG (66 lb) bag.
Current Developments in Self-Compacting Concrete Introduction Self-compacting concrete (SCC) is a flowing concrete mixture that is able to consolidate under its own weight.
Mixing: Place 75% of required potable water into mixer and slowly introduce entire bag of MS-S10 SCC.
Add balance of required water slowly while mixer is running, not exceeding maximum recommended volume of water.
Grout is required to be placed at a slump of 8 to 11 inches – a very wet mix – to flow into the grout space.
Excess water in the mix does not adversely affect grout strength as it is absorbed by surrounding masonry.
Clean the area to be repaired with potable water, leaving the concrete saturated but free of standing water (SSD).Materials for grout shall be measured in such a way that the required proportions of the grout materials are controlled and accurately measured.Grout shall be produced using one of the following procedures: grout materials mixed with water at the job site and ready-mixed grout transported to the job site.This abstract is a brief summary of the referenced standard.It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
