Masonry Block
The SIGMA block admixture range has been specially formulated to improve processing efficiency and enhance the properties of finished masonry blocks. Oscrete has produced this dedicated range of admixtures especially for the masonry block industry.
Improved concrete properties such as greater cohesion, lower friction and better compaction assist the producer to achieve a better quality product. Production benefits such as stronger blocks, faster lifting and improved water repellent characteristics can be achieved with the use of Oscrete's SIGMA admixtures.
