Testing for Green Compression Strength and Permeability

Permeability and green compression strength are among the important mechanical properties and considered much in the sand casting mould preparation. These molding sand properties play a vital role in determining the optimum moisture content for making green sand casting mould. Tailing sand is the residue mineral from tin extraction, which contains between 94% and 99.5% silica and in abundance

MASONRY MORTAR TESTING NCMA

Compressive Strength Testing of Field-Prepared Mortar. Compressive strength is one of the most commonly tested properties of field mortar. The test, described in ASTM C780, provides an indication of mortar consistency during construction, not as an indication of the compressive strength of the masonry, or even of the mortar in the wall. Compressive strength test results should be compared on a

Foundry sand testing Wikipedia

Foundry sand testing is a process used to determine if the foundry sand has the correct properties for a certain casting process. The sand is used to make moulds and cores via a pattern.In a sand casting foundry there are broadly two reasons for rejection of the casting — metal and sand — each of which has a large number of internal variables.
