Product Description

U Type Concrete Expansion Additive with high effect 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.

U Type Concrete Expansion Additive 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.

specifications︰	Magnesium Oxide (MgO): 5%Max; Water Ratio: 3.0%Max; Total Alkali Content: 0.40%Max; Chlorine Ion: 0.05%Max; Fineness: Specific Surface 250 m2/kg Min, Residue on 1.25mm Sieve 0.5%Max; Setting Time: Initial Setting 45 minutes Min, Final Setting 10 hours Max; Limited Expansion Ratio: In Water: 0.025%Min(7d), 0.10%Max(28d); In Air: -0.02%Min(21d); Compressive Strength (Method A / Method B): 25.0/20.0Mpa Min(7d), 45.0/40.0Mpa Min(28d); Breaking Strength (Method A / Method B): 4.5/3.5Mpa Min(7d), 6.5/5.5Mpa Min(28d) 。 Note: In Method A, applying Primary Standard Cement for testing, In method B, applying 42.5Mpa OPC for testing (C3A 6～8%，R2O ≤1%)
Advantages︰	low alkali (<0.4%), low applying quantity, low slump loss; 1. To confect anti-crack concrete, anti-seepage concrete, shrinkage compensated concrete.
