Features & Benefits

AfriSam High Strength Cement can be used on its own, extended with selected mineral components or with plasticisers. This product caters for an array of specialist concrete applications to produce a wide range of cost-effective solutions. Applications include flowable or self-compacting concrete and pumped concrete for slabs on the ground.

High early strength development: 
AfriSam High Strength Cement is known for its typical high early strength, offering you outstanding benefits in terms of time-saving and meeting production deadlines. This makes it suitable for construction and structural work, as well as brick and block making. Applications include post-tensioned and pre-stressed members, early stripping of formwork in fast-track construction, and concreting in cold weather.

Workability and durability: 
AfriSam High Strength Cement offers consistent quality. Due to its use of mineral components, this cement offers improved durability of concrete necessary in aggressive environments such as sewage treatment works and concrete structures in marine environments. The extremely fine particles of the mineral components act as nuclei for the formation of calcium silicate, giving a fine-filler effect and producing a denser and more homogenous microstructure in the hardened cement paste and in the aggregate interfacial zone.

High Strength Concrete

For 30 MPa (nominal at 28 days) this concrete mix is suitable for suspended structural beams and slabs; as well as precast items such as flagstones and heavy-duty surfaces such as workshop floors.

Ratio 1 : 3 : 3

1 part AfriSam High Strength Cement + 3 parts coarse sand + 3 parts stone.

Quantities per m³ of Concrete

To make a mix for 1 cubic metre of high-strength concrete you will need 6,59 bags of AfriSam High Strength Cement + 0,64 cubic metres of coarse sand + 0,64 cubic metres stone.

We suggest adding an extra 10% for wastage.

Mixing Table Guide

Ultra High Strength Concrete

A tensile strength of 45 MPa is suitable for suspended structural beams and slabs, columns and water retaining structures.

Ratio 1 : 2.5 : 2.5

1 Part AfriSam High Strength Cement + 2 ½ parts coarse sand and 2 ½ parts stone.

Quantities per m3 of Concrete

To make a mix for 1 cubic metre of Ultra High Strength Concrete you will need 7,7 bags of AfriSam High Strength Cement + 0,63 cubic metres of coarse sand + 0,63 cubic metres of stone.

We suggest adding an extra 10% for wastage.
