·The composite TCM tends to have an increased water uptake with increasing MgSO 4 content However the extent of the hydration of MgSO 4 in the composite shows a decreasing trend with the hydration rate of MgSO 4 increasing with the addition of diatomite This suggests that the diatomite improve the mass transfer of the composite TCM
·Hydraulic structures are subject to high risk of deterioration associated with cracking and sulfate chloride attack Application of Engineered Cementitious Composites ECC with self controlled tight microcracks and self healing capacities could potentially lead to enhanced durability performance of hydraulic structures even after the formation of cracks
·The microstructure mechanical properties and fracture behavior of polypropylene PP /barium sulfate BaSO4 composites were studied Four composite samples with different PP BaSO4 interface were
·Sulfate based SO42− polyanionic materials with low cost and ionic conduction break fresh ground for rocking chair systems But the high moisture sensitivity and limited conductivity led to their poor crystal stability and inferior alkaline ion intercalation chemistry Here we report the design of graphene based sandwich type nanoarchitecture for sulfate The three
