Concrete is a mixture of cement, fine aggregate, coarse aggregate and water. Concrete plays a vital role in the development of infrastructure Viz., buildings, industrial structures, bridges and highways etc. leading to utilization of large quantity of concrete. High Performance Concrete (HPC) is a concrete meeting special combinations of

In this paper, a type of typical locally available manufactured sand (MS) was utilized, and its effect on the properties of Ultra-High Performance Concrete (UHPC) were studied, based on physical and chemical points of views. According to the modified Andreasen and Andresen [1] (MAA) model, the natural river sand (RS) were partially replaced by ...

Coarser sand may be preferred as finer sand increases the water demand of concrete. Terribly fine sand might not be essential in High Performance Concrete. Coarse Aggregate : The coarse aggregate is the strongest and least porous component of concrete. The strength of High Performance Concrete is also controlled by the strength of the coarse ...

This paper researches on the feasibility of preparing ultra-high strength & high performance concrete with low quality fine aggregate, such as super fine sand (fineness moduls≤1.10), chippings and manufactured sand.

The heavyweight ultra-high performance concrete (HUHPC) was prepared with barite sand partially replaced by titanium-rich heavy slag sand (THS) at replacement proportion of 0%, 30%, 50%, 70% and 100% in this work. The results show that THS incorporation can effectively improve the mechanical properties and reduce the volume shrinkage of HUHPC. The HUHPC …

When concrete is placed in harsh conditions where aggressive chemicals are present, high-performance concrete that provides the highest levels of durability and technical performance is required. A...

was manufactured by Shandong Minglan Ganister Sand Material Co., Ltd., China. River sand with a fineness modulus of 2.7 and limestone with a maxi-mum size of 10 mm were used as aggregates. A polycarboxylic-acid-type superplasticiser was dosed to maintain the fresh concrete slump in the 150 to 200 mm range. The performance index of the cement
