U Concrete Expansion Additive can replace cement by same weight; the amount of type U Concrete Expansion Admixture and cement should be more 320kg/m3. C3A content in cement is more 8%, it is necessary to reduce the mixing quantity of type U Concrete Expansion Additive in order to avoid large loss of early strength of concrete.

Mud loss can occur mainly due to 3 reasons 1. The formation is so unconsolidated that the drilling mud spreads in every possible direction (usually occurs during top hole drilling) 2. Your mud hydrostatic force or ECD is higher than the fracture p...
US demand for oilfield chemicals will rise percent annually to billion in 2019. Stimulation chemicals and drilling fluid additives will remain the largest and fastest growing types, but will slow considerably from the rapid pace of the period. Key trends include a shift toward slickwater fracturing fluids and highperformance drilling muds.
slump. The rate of slump loss, however, is not reduced and in most cases is increased (Fig. 64). Rapid slump loss results in reduced workability and less time to place concrete. An increase in strength is generally obtained with waterreducing admixtures as the watercement ratio is 107 Chapter 6 Admixtures for Concrete Table 61.
