On another side, if the cement content, slump, water-cement ratio, aggregate angularity, temperature, and a decrease in the proportion of the coarse aggregate to fine aggregate will increase water demand. The layout of the piping system should be performed with the requirements of piping stress and pipe supports in mind (i.e., sufficient flexibility for thermal expansion; proper pipe routing so that simple and economical pipe supports can be This British Standard is set out to follow, in broad terms, the sequence of a ground investigation from initial considerations through the phased design and implementation of an investigation programme and its reporting, to the continuing investigation during and after construction. /AIS false The coarse aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a coarse aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. Conversely, sand, stonedust, and other sharply angular, aggregate materials can be abrasive to the hoof wall.

Angularity: The sharpness of edges and corners of particles. It also seems that the particles angularity has a strong influence on packing density: de Larrard (1999) reported that rounded aggregates give a packing density close to 0.60 while crushed aggregates packing gives values between 0.50 and 0.57.
