Introduction

Paver blocks are a versatile and durable option for paving surfaces, offering an aesthetic and functional solution to outdoor spaces. The process of manufacturing paver blocks involves several stages, each critical in ensuring the quality and durability of the final product.

Materials Required

The primary materials used in the production of paver blocks include cement (Portland cement or OPC), aggregates (fine and coarse, typically sand and crushed stone), water, and chemical admixtures if necessary. The typical proportion of these materials is 1 part cement to 3 parts aggregate by volume.

Process of Making Paver Blocks

Mixing

The mixing stage involves combining the cement, aggregates, and water. This can be done using a batching plant to ensure precision. Admixtures are added to modify the properties of the mix, such as improving flowability or setting time. A typical water-cement ratio ranges from 0.4 to 0.6 depending on the desired workability.

Moulding

The prepared mix is then cast into moulds which define the shape and size of the paver blocks. This is usually done using hydraulic press machines which apply pressure to compact the mixture. The pressure applied is typically between 7-10 MPa, ensuring adequate compaction and strength of the blocks.

Curing

Curing is a crucial step that involves controlling the moisture content and temperature of the blocks to achieve optimal hydration of cement. Standard curing duration is 21 days, but this can be reduced to 7 days with steam curing at 60°C, which accelerates the strength development.

Testing

To ensure compliance with industry standards, paver blocks are subjected to rigorous tests. Compressive strength tests should show results above 25 MPa for pedestrian use and 40 MPa for vehicular use. Other tests include water absorption, which should not exceed 6%, and dimensional tolerance checks within 2mm of specifications.
