Atlas Readymix Concrete - Karachi, Pakistan

Ready-mix Concrete is a type of concrete that is manufactured in a factory according to a set recipe, and then delivered to a worksite, often by truck. This results in a precise mixture, allowing special concrete mixtures to be developed and implemented on construction sites. The first ready-mix factory was built in the 1930s, but the industry did not begin to expand significantly until the 1960s, and it has continued to grow since then. Ready-mix concrete is sometimes preferred to on-site concrete mixing because of the precision of the mixture and reduced worksite confusion. However, using a pre-determined concrete mixture reduces flexibility, both in the supply chain and in the actual components of the concrete.

Self-Consolidating Concrete (SCC) or Self-Compacting Concrete, as it’s sometimes known, arrived as a revolution in the field of concrete technology. The concept was proposed by Professor Hajime Okamura of Kochi University of Technology, Japan, in 1986 as a solution to the growing durability concerns of the Japanese government. During his research, Okamura found that the main cause of the poor durability performances of Japanese concrete in structures was the inadequate consolidation of the concrete in the casting operations. By developing concrete that self-consolidated, he eliminated the main cause for the poor durability performance of their concrete. By 1988, the concept was developed and ready for the first real-scale tests.

Atlas Readymix is one of the few companies in Pakistan which are doing research on Self-Compacting Concrete (SCC). This innovative concept in concrete, which may proof to be economically and environmentally viable in modern day construction activities, for the following reasons: Self Compacting Concrete

- Faster construction
- Better surface finishes
- Improved durability factor
- Safer work environment
- Less pollution
- Less manpower on site
- Easier placing
- Reduced noise level due to absence of vibration
