{"title":"Natural Cement","description":"\u003cp class=\"MsoNormal\" style=\"margin-bottom: 7.0pt;\"\u003eNatural Cement has been manufacturing Natcem products in Yorkshire for over 30 years, supplying fast-setting mortars and grouts based on a natural cement binder derived from argillaceous limestone — a material with over 200 years of documented use in construction. The result is a product range that is inherently waterproof, chemically resistant and fast-curing without the need for steel primers, bonding agents or curing compounds.\u003cbr\u003eNatcem mortars are suitable for concrete repair, waterproof renders, floor screeds, grouting, void filling, pointing and general repairs. Key products include Natcem 35, a fast-setting mortar that begins to set after 35 minutes and is fully set in 40; Natcem DW, formulated for use in contact with potable water; and Natcem AC, a fine-graded mortar suitable from 3mm thickness for precision applications. All products are DWI Reg.31 approved for potable water contact, WRAS approved and can be used in cold, wet and underwater conditions. With a low carbon footprint and no synthetic additives, Natcem is also an environmentally responsible choice.

Formulated from a blend of natural cement binder, retarder and specially selected graded aggregates passing a 2mm sieve, it contains no chemical additives and requires only the addition of water. An extended setting time of 55–60 minutes at 20°C provides longer workability than faster-setting natural cement mortars, making it well suited to larger tanking projects. Achieves 26 MPa compressive strength at 28 days, sets underwater and can be used down to 0°C including in freezing conditions. Can be overcoated within one hour of setting.
