Grey 40 % Mgo Low Heat Acid Proof M Sand

It is made from a combination of natural ingredients such as quartz, feldspar, and other minerals that are resistant to acid. This type of sand is often used for acid tanks, acid-resistant floors, and other acid-resistant surfaces. This type of sand is also acid-proof and has a low so3 content of 0.5% and a high mg o content of 40%. The sand has a low bending strength of around 30%, which makes it ideal for use in projects that require a low amount of flexibility. Its initial setting time is 30 minutes, which is comparatively lower than other sands. The sand is specially processed to reduce the amount of heat generated during its production, making it more suitable for use in areas where temperatures can reach extreme levels.
