1800 Kilogram Eco Friendly Weather Resistance Silicate Foundry Sand Bending Strength: Higher Average

This foundry sand is weather-resistant, high-quality sand produced using silicate cement which combines the best properties of natural and synthetic sand. This gives it well-known advantages such as extreme wear resistance, excellent compressive strength, and a very low water absorption rate. This sand is a kind of high temperature resistant fine sand with a good rating in refractory and insulator as well as non-toxic, with lightweight, and high strength. Ita s used in the foundry and ceramics industry as a binder for vat lining, concrete cores, and making glass. It contains 4% of SO3 and 40-42% MgO with a low heat of hydration and compressive strength of 10.34 kilopascals.
