Bagged Normal Cement

Normal Cement is a high quality general purpose bagged cement and is suitable for all general concreting, block laying and plastering applications

Application 

Normal Cement is suitable for a wide range of applications where no special or unusual considerations arise. Typical applications include use in site-mixed concrete for foundations, paths, etc., in small precast elements and in mortars, renders and grouts.  Mortar mixes should have improved workability properties, compared with traditional cement based only on cement clinker, resulting in a more cohesive mortar or render mix, with better handling and finish characteristics.

Setting time

I.S. EN 197-1 requires a minimum initial setting time of 75 minutes. Initial set for Normal Cement typically exceeds 100 minutes. Strength: Minimum compressive strengths for standard mortar prisms of 16 N/mm2 at 7 days and 32.5 N/mm2 at 28 days are stipulated in I.S.EN 197-1 for class 32.5N cement in accordance with particular compliance rules. Typical mortar prism strengths of Normal Cement are in the range 30-38 N/mm2 at 7 days and 40-50 N/mm2 at 28 days. Concrete and mortar strength is significantly affected by mix constituents and proportions, ambient temperature and curing conditions. A durable concrete requires an adequate cement content and a low water / cement ratio. The correct mix ratio of cement:sand and the use of suitable mortar admixtures or lime is necessary to provide good durability in mortars or plasters. Guidance is available in Irish Standards for suitable concrete and mortar mixes for various exposure conditions.

Chemical Composition

Cement clinker consists predominantly of compounds formed from Calcium, Silica, Alumina and Iron. Calcium sulfate in the form of gypsum is added to cement to control the setting time. Limestone (Calcium Carbonate), complying with specified requirements in I.S. EN 197-1, is present in the range 6% - 20% in CEM II/A-L Normal Cement, as stipulated in I.S. EN 197-1. Specific data on chemical and compound composition of Normal Cement is available on request.

This product has been specifically designed to reduce the carbon intensity of cement production and to provide enhanced workability in block laying and plastering applications. The quality of all Normal Cement produced by Irish Cement is guaranteed to meet, in full, the requirements of Irish Standard I.S. EN 197-1 ‘Cement Part 1: Composition, Specifications and Conformity Criteria for Common Cements’, and the product is independently certified by the National Standards Authority of Ireland and is CE marked. Normal Cement is produced by grinding a combination of cement clinker and selected limestone and grinding aids, along with a small quantity of gypsum, to produce the final fine grey powder. Cement clinker is made by fusing together, at high temperatures, a precisely controlled blend of very finely ground limestone and shale.
