The surfaces in contact with the aggregate shall be machined and

Estimating Soil Texture – CMG #S14, page 3 The soil texture triangle gives names associated with various combinations of sand, silt and clay. A coarse-textured or sandy soil is one comprised primarily of sand-sized particles. A fine-textured or clayey soil is one dominated by tiny clay particles.

other. Dry, powdered silt and clay are indistinguishable from each other visually but are easily identified by their characteristics when wet or moist. Recognition of fines as having either silt or clay behavior is an essential part of the Unified Soil Classification System. Silts are slightly plastic or nonplastic fines.

2.1 Object — This test involves visual inspection, and a segregation of the constituents of coarse and fine aggregates according to petrographic and chemical differences. 2.2 Apparatus 2.2.1 Screens conforming to the IS Sieve designations given below: 150 …

Concept: As per I. S. 2386 - Part 1, a sieve size of 2 mm represents that each hole in a sieve is of 2 mm square shape. According to the ISSC system size of coarse aggregates starts from 0.075 mm or 75 microns and ends at 80 mm. So sieve of 4.75 mm and 10 mm are normally used for classification in coarse aggregates. The table below shows the tabular data for different sieve suitable for ...
