In due course, the gypsum is converted to ettringite which, having a higher volume than the original C 3 A, causes expansion and disruption of the cement paste. Cements having a low C 3 A content are manufactured as sulfate-resisting Portland cements. Figg (1983) identified three main types of failure due to sulfate attack. The first is the ...

Several synthetic binders can be used for soil stabilisation instead of cement or hydrated limes including calcium sulfate dihydrate, commonly known as gypsum (CaSO 4.H 2 O), tetrasodiumpyrophosphate (Na 4.P 2 O 7. 10 H 2 O), and calcium, sodium and potassium salts (Burroughs, 2001).In addition, several organic chemicals including fatty …
We applied annual applications of calcitic lime (1,000 lb/acre) or gypsum (500 lb) to a very acidic blueberry soil. Gypsum clearly increased pH, but not nearly as much as lime. If the initial pH of this soil was 6.0 or 7.0, gypsum would likely have had no effect on pH. Nutrient value. Gypsum contains about 22% calcium and 18% sulfur.

POTASSIUM SULFATE FERTILIZER PRODUCTION LINE. Potassium sulfate is the inorganic compound with formula K2SO4. It is commonly used in fertilizers, providing both potassium and sulfur to soils. Potassium sulfate is a type of fertilizer which can be in granular or powder structure containing 50% potassium (K).
Flue-gas desulphurization (FGD) gypsum is a highly prevalent industrial by-product worldwide, which can be an excellent alternative to natural gypsum due to its high content of CaSO4·2H2O. The preparation of α-calcium sulfate hemihydrate is a high-value pathway for the efficient use of FGD gypsum. Here, a dynamic method, or an improved …

Common Misconceptions about Gypsum. Gypsum, composed of calcium sulfate dihydrate (CaSO₄·2H₂O), provides calcium and sulfur to the soil without affecting its pH. This is because the sulfate in gypsum is already in a soluble form, readily available to plants without undergoing chemical reactions that would alter the soil's acidity or ...

Potassium sulphate is a very effective accelerator for the setting process. Adding it results in the formation of the distinct crystalline double salt known as syngenite: K 2 Ca(SO 4) 2 ·H 2 O. The solubility of this compound, in g/L, is apparently higher than that of dihydrate, but not if expressed in terms of molarity with respect to the calcium it contains:
Introduction. Interest in potassium sulphate stems mainly from its use as a potash fertilizer for crops which are sensitive to chlorides.
