Bentonite Clay's Role in Green Sand Metalcasting

In a green sand system, the clay and water combine to form a clay bridge that binds sand grains to one another. This bond­ing mechanism is a hydrated system that requires water, energy, time and technical expertise. Two types of bentonite clay are typically used: calcium bentonite and sodium bentonite.

Bentonite - an overview ScienceDirect Topics

The bentonite forms a pliable bond with the sand grains, so the mixture holds its shape well. Molten metal is then poured into the impression to make the casting. When complete, the bentonite and sand mold can then be broken away from the casting and reused. Bentonite is used as a binder for food pellets for animals and poultry and as a carrier for food supplements.

Alkali–silica reaction - Wikipedia

The alkali–silica reaction (ASR), more commonly known as "concrete cancer", is a deleterious swelling reaction that occurs over time in concrete between the highly alkaline cement paste and the reactive amorphous (i.e., non-crystalline) silica found in many common aggregates, given sufficient moisture.. This deleterious chemical reaction causes the expansion of the altered aggregate by the ...

Alkali–silica reaction - Wikipedia

The mechanism of ASR causing the deterioration of concrete can thus be described in four steps as follows: The very basic solution (NaOH / KOH) attacks the siliceous aggregates (silicic acid dissolution at high pH), converting the poorly crystallised or amorphous silica to a soluble but very viscous alkali silicate gel (N-S-H, K-S-H).
