Western Proppants (WP) is the only in-basin source for high quality frac sand in southeast Wyoming. Located in Goshen County, Wyoming, we are also the only mine with close access to both the Powder River Basin and DJ Basin. With crush strength exceeding 8,000 PSI, WP’s products are suitable for all in-basin formations and applications.

You can use crushed sand as well as natural river sand for the trimix work. Of course, crushed sand is better provided it meets all standards and specifications. Crushed sand has higher compressive and flexural strength. But it is not easily available in village/city which are far from the quarrying (crusher plant).

Sand Cement Block Crush Strength. The addition of fungal treated sand enhanced the strength gain of concrete by formation of bio-mineral which led to plugging of pores of cement sand matrix. The rate of strength gain of WFS concrete was found higher than conventional concrete at later ages 90365 days.

Strength is found using the crush resistance test. The crush resistance test is used to determine a “K Value,” which is the pressure at which 10% or more of the sand starts to break into fines. High quality frac sand often has K values of 5K, 8K, 9K. Resin coated frac sand and ceramic proppants have even higher K values.

Answer (1 of 2): Compressive strength of cement- sand mortar would depend on 1.) Grade of cement (43/53) 2.) nature of sand used (river/crushed sand which would have bearing on water requirement if no admixture is used for desired workability, if any) 3.) quantum of water 4.)

IS Code for Silt Content Test of Sand: IS 2386-2 (1963) Silt Content In Sand Limit. Silt content in the sand must not exceed 8% as per is IS 2386-2. If the silt content on sand exceed 8 % that that may result in a reduction in binding capacity of mixed materials, which also affects the strength and durability of the final product.

When crush strength is exceeded, the grain breaks and produces pieces, or fines. The fines are weighed as a percent of the grain size to calculate a k-value that designates the level of crush resistance. High-quality sand with an 8K value means that at 8,000 psi, it produces no more than 10% fines by weight.

The source of crushed sand is a quarry. It is manufactured by crushing rock, quarry stones or larger aggregate pieces into sand size particles in a factory or quarry. The compressive strength as well as the flexural strength of concrete made from crushed sand is higher than natural sand. Crushed sand is also eco-friendly because it causes less damage to the environment as compared to natural sand.

compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area. Rock strength has been found to be size dependent because of the cracks and fissures that are often present in the material. This is illustrated from the results of tests on three rock types in Fig. 8.2. The size

Disadvantages of M-Sand. Crushed sand can be of coarser and angular texture. This can lead to more water and cement requirement to achieve the expected workability. Manufactured sand can contain larger amounts of micro fine particles than natural sand, This can affect the strength and workability of the concrete.
