Type UEA High-efficiency Expansion Additive for concrete from Shezhen Chenggong Building aterials Co., Ltd.(www.chngn.com), is made of the clinker of Calcium Aluminate – Calcium Sulphoaluminate. It is a special admixture for the expansion concrete of Portland Cement and Ordinary Portland Cement.
Type UEA High-efficiency Expansion Additive for concrete has very good expansion performance, and also because of its low alkali characteristics, it can inhibit alkali-aggregate reaction and it can reduce the slump loss of concrete due to high alkali in cement concrete.
Recommended added quantity: 8-10% of ceme by weight.
Packing: 50kg/bag, and/or 1MT big bag.
