Examples of Type A cohesive soils are often: clay, silty clay, sandy clay, clay loam and, in some cases, silty clay loam and sandy clay loam. (No soil is Type A if it is fissured, is subject to vibration of any type, has previously been disturbed, is part of a sloped, layered system where the layers dip into the excavation on a slope of 4 horizontal to 1 vertical (4H:1V) or greater, or has ...
processing of sand and gravel for a specific market involves the use of different combinations of washers, screens, and classifiers to segregate particle sizes; crushers to reduce oversized material; and storage and loading facilities.

FINE: fine and coarse sands and crusher fines. Sand should be concreting sand and not brickies sand or plasterers sand. Aggregates should be: STRONG and HARD so as to give a strong final concrete – crumbly or flakey rock such as sandstone should not be used. DURABLE to stand up to wear and tear and weathering. CHEMICALLY INACTIVE so that the aggregates don't react with the cement. CLEAN ...
Bearing capacity is the capacity of soil to support the loads applied to the ground. The bearing capacity of the soil is the maximum average contact pressure between the foundation and the soil which should not produce shear failure in the soil. Ultimate bearing capacity is the theoretical maximum pressure that can be supported without failure.
Lime should be used if the sand lacks fine material or is single sized, as such sands tend to produce mortar with poor workability unless lime is included in the mix. Lime also helps the fresh mortar to retain water when it is placed against dry cement bricks or blocks and helps to prevent cracking of the hardened mortar. For Class I mortar, a maximum of 10 kg of lime is permitted per 50 kg of ...
predominantly in sand and silt fractions, and are weathering resistant (quartz, feldspars); ... Porosity in soils varies between (sands, silts) to (clays) to (peat), and is largely determined by the soil bulk density: air water solids.

· The Disadvantages. Workability issues: Manufactured sand can be of a coarser and angular texture than natural sand, which is smooth and rounded due to natural gradation. This can lead to more water and cement requirement to achieve the expected workability, leading to increased costs. Larger proportion of micro fines: Manufactured sand can ...
