## Description

Concrete additive-Water reducer-Super plasticizer 33lb. paper bag .High-performance super plasticizer for cement based construction materials. GlobMarble super plasticizer is especially optimized for plastification and water reduction of cementitious construction materials. Super plasticizer provides an excellent development of early strength. Many important characteristics of concrete are influenced by the ratio (by weight) of water to cementitious materials (w/cm) used in the mixture. By reducing the amount of water. The cement paste will have higher density, which result in higher paste quality. An increase in paste quality will yield higher compressive and flexural strength, lower permeability, increase resistance to weathering, improve the bond of concrete and reinforcement, reduce the volume change from drying and wetting, and reduce shrinkage cracking tendencies. Super plasticizer dosage is 0.5- 1 % by weigh of cementitious material. For 90 lbs(40 kg) (bag of cement) you'll need approximately0.5(0.20 kg) - 1 lb(0.45 kg) of GlobMarbe super plasticizer. Characteristics / Chemistry Free-flowing, spray dried powder of modified polycarboxylic ether. Fields of application are : Self-levelling underlayments (SLU); Feather-edge products; Non-shrink grouts Cementitious floor screeds; Cementitious fast-setting, self-levelling floor screeds; Repair, Injection mortars; Tile adhesives and joint fillers Dry-mix concrete. pH-value (20 °C), 20 % solution - 6.5 to 8.5; Dosage recommendation, [%] by weight of cementitious material 0.05 to 1.00 by Cement weight. Further Technical Data Superplasticizer based on latest polymer technology.. Available Packaging 1lb. sample bag 33lb. paper bag 1650lb. 50 paper bags(1 pallet)

Making pavers with ready mix concrete and before using this they were weak and crumbling. With this plasticizer you don’t need very much water which makes them much stronger
