Cement 42,50R – 25 kg bags

Cement 42,50R – 25 kg bags

We Supply Portland Cement in accordance with EN 197-1:2011 CEM I Class 42,50R, in  25kg bags.

The quality of our bulk cement meets the requirements of EN 197-1 “Cement Part 1: Composition, Specifications and Conformity Criteria for Common Cements” and carries the CE mark from the producer.

This cement is a fast setting cement with a mechanical compressive strength development Minimum values

2 days:  20,0 MPa

28 days:  42,5 MPa

The bags are supplied in pre-slung packages with lifting straps – with 71 bags per pack

We can supply small amount of bags up to full lorry loads.

The cement bags are made up of 4 layers, 3 ply kraft paper with 1 layer of plastic to make the sealed bags weather resistant for shorter periods. We do however always recommend that cement is stored dry and under cover.

Health & Safety

Cement is irritating to eyes, respiratory system and skin. Keep out of the reach of children. Avoid contact with the skin and eyes as this may cause serious burns and ulcerations or an acute allergic reaction in some people. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. After contact with skin, wash immediately with plenty of water. Wear suitable protective clothing.

We Supply Portland Cement according with EN 197-1:2011 CEM I Class 52,50R, in bulk or in 1.50ton sealed bulk bags.

The quality of our bulk cement meet the requirements according to EN 197-1 “Cement Part 1: Composition, Specifications and Conformity Criteria for Common Cements” and carries the CE mark by the producer. The cement is currently not accredited in the UK but we are in process of achieving the required accreditation.

This cement is a fast setting, High early strength cement with a mechanical compressive strength development Minimum values

2 days:  30,0 MPa

28 days:  52,5 MPa

We supply this grade to industrial users for use in readymix concrete batching plants or for use in volumetric mixers.

This cement is supplied using bulk powder tankers for blowing into silos or our customers collect from our site using their own tankers.

We can also supply this cement in 1.50ton sealed bulk bags loaded and delivered/collected using curtain siders or flatbed lorries. The bulk bags are sealed to be weather proof and can be stored outside for shorter periods of time, We do however always recommend that cement is stored dry and under cover.

Routine product test data covering the key physical and chemical parameters is made available on a weekly basis on request.

Looking for Concrete

Looking for Concrete

Concrete Mixes (A general guide*)

Aggregates

Aggregates are used to give body and strength to a concrete or mortar mix. Coarse aggregate is small stones, usually less than 20 mm in diameter, and fine aggregate is basically sand. Sharp Sand (which has larger grains) is used for concreting or laying paving slabs and Soft Sand is used for bricklaying, etc. It is also possible to buy mixed aggregate containing both coarse and fine aggregates.

In general, the aggregate component of a concrete or mortar mix is usually several times that of the cement. For example, a simple sand and cement mix should be at least 3 part sand (the aggregate) to one part cement. A strong concrete mix would be something like 1:3:5 (Cement, Sand, Coarse Gravel). In this case, both the sand and gravel are the aggregate.

General Purpose Concrete – 1:2:3 mix

Ideal for most uses except foundations and exposed paving. It is composed of one part cement, two parts sand and three parts coarse aggregate. If using combined aggregate, this mix would be 1:4, one part cement to four parts combined aggregate.

Foundation Concrete – 1:2 ½:3 ½ mix

Ideal for wall foundations or bases and laying paving slabs, etc. One part cement, two and a half sand and three and a half coarse aggregate. If using combined aggregate, this mix would be 1:5.

Paving Concrete – 1:1 ½:2 ½ mix

Used for exposed paving such as driveways and garage floors. One part cement, one and a half parts sand and two and a half parts coarse aggregate. Combined aggregate would need a mix of 1:3 ½.

Mortar Mixes

Standard Mortar 1:5 mix

Used for internal or sheltered bricklaying. Mix one part cement to 5 parts soft sand. Add a small amount of lime or one part plasticizer to increase the workability. This type of mortar mix is perfect for use in an internal block wall partition.

Strong Mortar 1:4 mix

Used for exposed brickwork. Mix one part cement to 4 parts soft sand. Again, add a small amount of lime or plasticizer to increase the workability.
