The effect of superplasticizer (SP) on the performance of ultra-high-performance concrete (UHPC) and ultra-high-performance fiber-reinforced concrete (UHPFRC) has been systematically investigated aiming to optimize the use of SP. The slump flow. and V-funnel time were employed to evaluate the impact of SP on the workability. while compressive strength had been used for mechanical prop... https://trendingcustomes.shop/product-category/usa-map-wooden-puzzle/
