Penetrating sealers often require the use of special cleaners which both clean and top up the repellent ingredient left on the stone surface. These sealers are often breathable to a certain degree, but do not penetrate deeply enough (generally less than 1mm) to be effective against salt attack, such as efflorescence and spalling.
Agricultural lime, also called aglime, agricultural limestone, garden lime or liming, is a soil additive made from pulverized limestone or chalk. The primary active component is calcium carbonate . Additional chemicals vary depending on the mineral source and may include calcium oxide .
For natural hydraulic lime (NHL) mortars, the lime is obtained from limestone naturally containing a sufficient percentage of silica and/or alumina. Artificial hydraulic lime is produced by introducing specific types and quantities of additives to the source of lime during the burning process, or adding a pozzolan to non-hydraulic lime.
Concrete sealers are applied to concrete to protect it from surface damage, corrosion, and staining. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing.
In the lime industry, limestone is a general term for rocks that contain 80% or more of calcium or magnesium carbonate, including marble, chalk, oolite, and marl.Further classification is done by composition as high calcium, argillaceous (clayey), silicious, conglomerate, magnesian, dolomite, and other limestones.

The main components of LC3 cements are clinker, calcined clay, limestone, and gypsum. [24] [25] [26] The fresh concrete production involves synergetic hydration.[10] [27] Adding large amounts of calcined clay and ground limestone to the dry cement powder, [28] [29] when adding water to the mix for making concrete, cement and additives start to hydrate and the soluble aluminates released in ...

Zinc L-carnosine (beta-alanyl-L-histidinato zinc [1]) (N-(3-aminopropionyl)-L-histidinato zinc [2]), often simply called zinc carnosine, and also known as polaprezinc, [3] is a mucosal protective [4] [5] chelate compound of zinc and L-carnosine invented by Hamari Chemicals, Ltd. [6] [7] It is a quadridentate 1:1 complex of a polymeric nature. [6]
