Cement additive mortar use price per ton CSA expansive agent

Sepecifications:

It is A kind of expanding agent based on calcium sulphoaluminate and calcium oxide, with double expansion prpoerties.In morden construction, the crack of buildings and decorations is becoming a headache of engineers.When the crack happened, it mainly has two reasons.They are dry shrinkage of hydraulic materials and temperature change caused volume change. CSA expansive agent is designed to mix in dry mortar and concrete ect,when it hydrated，it produce ettringite to compensative the shrinkage when the concrete turn dry. 

Characteristic:

1. Low alkali. This product is made by clinker with main raw mineral material of  anhydrous calcium sulfo aluminate and calcium oxide, add sutiable gypsum etc. not contain any natural alum stone or fired alum stone，so its alkali percentage is very low（R20≤0.3%),no harm to the futher strength of concrete.

2. Short expansion stability. No obvious expansion after 14 days.

3.High efficiency expansion. Can acheive statified expansion effect by only add 6~8%.

4.Low dosage, comparing to other expansive agent in domestic market(usually 25~50%), our CSA expansive agent dosage is the lowest. Also low dosage is the Effective guarantee for reducing the cost of concrete project.

Application:

CSA expansive agent has the same application like other expanding agent UEA,CEA.Particularly applicable to the following construction and parts：

1. Forstructural self-waterproofing construction.
2. Effectively preventing cracking or leakage of concrete. 
3. To extend the space length of post casting zone of cast-in-place overlengthstructure.
4.To control the crack producing result of temperature difference in largesized structural concrete. 
5. For rigid roofing. Making non-shrinkage cements..
