Allows concrete to be very fluid and workable and can be placed with little to no vibration or compaction. Allows concrete slump and workability of concrete to increase while lowering the water/cement ratio. The product also increases compressive strength. The newage product has the same shelf life as normal hydration concrete.
The use of this additive improves early and cured compressive strength. CemFix is a complex copolymer that assists in wetting fly ash cement admixtures. It also regulates the distribution of water between the cement and pozzolanic ash. In so doing the cement hydrates fully and develops maximum cured strength.

Oct 25, 2017· The concrete with fly ash or silica fume was stronger than concrete made with just Portland cement. And the presence of irradiated plastic along with fly ash strengthened the concrete even further, increasing its strength by up to 15 percent compared with samples made just with Portland cement, particularly in samples with highdose irradiated ...
Apr 22, 2019· The strength of a concrete block or brick wall depends on the mortar holding the blocks together. Mortars that are rich in lime are weaker than mortars that are heavy in cement. For comparison, a limedense mortar can withstand around 350 psi, while a highcement mortar can withstand 3000 psi.
Highstrength concrete. Highstrength concrete has a compressive strength greater than 40 MPa (5800 psi). In the UK, BS EN 2061 defines High strength concrete as concrete with a compressive strength class higher than C50/60. Highstrength concrete is made by lowering the watercement (W/C) ratio to or lower.
