Jul 02,  · The influence of four factors (water-binder ratio, recycled coarse aggregate replacement rate, fly ash substitution rate, and superplasticizer content) on the workabilities and mechanical properties of recycled coarse aggregate self-compacting concrete (RCASCC) was studied using the orthogonal test method. Based on the orthogonal test design and range analysis method of the fresh

Jun 29,  · Lightweight Concrete Solutions of Etobicoke, Ontario are an excellent example of the promising and successful use of lightweight concrete on the jobsite. Founded by Director Chris Calvin in , they are the industry leader of lightweight concrete, and their focus is on developing the highest quality products for their clients.

Jun 17,  · Self-compacting concrete with a similar water cement or cement binder ratio will usually have a slightly higher strength compared with traditional vibrated concrete, due to the lack of vibration giving an improved interface between the aggregate and hardened paste. The concrete mix of SCC must be placed at a relatively higher velocity than that of regular concrete.

In order to avoid such problems, mix design method of high performance self-compacting concrete is recommended for the lightweight concrete. Therefore, this study introduces a production of self-compacting concrete, PF-modified and improved version of Nan-Su's mix design method.

The paper is aimed to review the more recent research of physical properties of lightweight aggregates used in developing mix design of lightweight self-compacting concrete. In design, the mix

Fast-Setting Concrete Mix: When you need to support a fence or mailbox post, or create a small concrete slab, fast-setting concrete makes a great choice. This sets in just 20 to 40 minutes. High-Strength Concrete Mix: When durability is key, high-strength concrete makes a great choice. This is ideal for foundations, footers and heavy equipment
