Workers then expose aggregate by brushing the wet cement with a nylon bristled brush, progressively pushing the water and cement mixture across the slab. The installer must complete the brushing and washing process in a single pass. Wetting and brushing the concrete a second time causes excessive weakening in the remaining cement paste.
Adding the Aggregates Aggregates are normally added using one of three methods: 1. Integral mixing In integral mixing, aggregates are added to the mix at the batching plant. The concrete is placed, vibrated, screeded and bull-floated, resulting in approximately 2mm coverage of cement paste over the aggregates. 2. Topping mix
