2020.6.19 In case of natural round gravel aggregate-based concrete, the addition of silica fume brought about an increase in its compressive strength. In turn, basalt-based concrete exhibited notably lower compressive strength values due to significantly higher porosity within the range of more than 70 μm.

2008.7.26 3.2 Wet packing method. The wet packing method involved the following steps: mixing with water, filling into a container, compaction (if any) and bulk density measurement. First, the aggregate was thoroughly mixed with a predetermined amount of water. Then, the mixture was filled into a container.

2020.6.27 It is generally believed that in engineering practice, the maximum density curve is used to design gradation and the aggregate density is maximum when n is 0.45. Therefore, n equals to 0.45 in this experiment is considered as the optimal gradation density. 3.2. Dominant Aggregate Size Range

2019.11.11 To provide clarity and avoid confusion, we will stay with the definition that gravel cannot refer to crushed stone and must remain in its natural state. There are three types of natural rock and stone: igneous, sedimentary, and metamorphic. Igneous: Igneous rocks are formed after molten rock or lava solidifies.

The voids are interconnected to produce a porous open-textured concrete with reduced density, strength and shrinkage. Density depends mainly on the type and grading of the aggregate. The lowest densities are achieved with single-sized coarse aggregate. Maximum aggregate size can range from 7 to 75 mm 1 but is usually from 10 to 20 mm.
