A composite cement formulation, engineered specifically for road construction and stabilisation tasks, is said to enhance the stability and strength of road materials by improving the properties of the soil.

Available from construction materials supplier AfriSam, the cement is designed to optimise the properties of soils used in road construction by reducing its plasticity and enhancing soils’ strength and stability.

The formulation of AfriSam Roadstab Cement aims to address the requirements of road construction projects by ensuring the durability and stability of road bases. The product’s composition is designed to contribute to its efficacy, particularly in working with challenging soil types like clay, helping to improve the workability of the cement in various soil conditions and facilitating easier handling and application during the construction process.

Stabilisation using cement is also said to improve the properties of granular materials. When cementitious material is mixed with granular material in predetermined portions and is adequately mixed, compacted and cured, the result is a bound material with significant strength.

AfriSam notes that an important advantage of its Roadstab Cement is its extended open working times as it provides enough time for the proper placement and compaction of materials. The company explains that this type of flexibility in the construction timeline is crucial for achieving optimal results in soil stabilisation, ensuring that the stabilised layers meet the required standards for strength and durability.

The product is suitable for use with a variety of road material types and its ability to reduce soil plasticity makes it a key component for constructing durable and stable roads.
