Step-by-step

Follow a complete solution

Concrete slab poured under a hot sun from a chute, with an admixture drop and a curing spray coating the finished part Hot-weather concreting In a Pakistani summer, concrete loses slump in the truck, sets before it is finished and cracks if it dries early. Use a hot-climate superplasticiser or retarder, pour in the cooler hours and start curing straight away. 6 steps Wall cast in insulated timber formwork in snowy weather, with an accelerator dose going into a truck mixer drum Cold-weather concreting In winter in Murree, Quetta and the northern areas, fresh concrete can freeze or gain strength too slowly to strip the forms. An antifreeze accelerator, warm materials and insulation keep the work moving. 6 steps Truck mixer with an admixture dose discharging into a concrete pump that pipes the mix up to an upper floor slab High-performance ready-mix concrete Ready-mix plants supplying high-strength, pumped or long-haul concrete need a superplasticiser that holds slump, cuts water and works with GGBS, fly ash or microsilica. Durability admixtures cover corrosion and air entrainment where the specification asks for them. 6 steps Fluid concrete flowing level through dense reinforcement in a sealed beam form, with no vibrator, after an admixture dose Self-compacting concrete (SCC) Self-compacting concrete flows into congested reinforcement and fills forms without vibration. It needs a high-range polycarboxylate superplasticiser, an SCC mix design and strong, well-sealed formwork. 6 steps Precast element cast in a steel mould on a casting bed beside a finished unit being lifted out early by a crane hook Precast concrete production Precast yards need early strength for quick stripping and mould turnover, or semi-dry mixes that fill moulds evenly for pavers, blocks and kerbs. Choose the admixture by process: wet-cast or semi-dry. 7 steps Thick raft placed in layers by a pump hose, with a temperature sensor and a chart showing a lower, flatter heat curve Mass concrete & set retarding Thick rafts, dams, bridge piers and large foundations heat up as the cement hydrates and can crack, and big pours risk cold joints. A retarding superplasticiser or set retarder spreads the heat release and keeps each layer workable until the next one arrives. 6 steps

Fresh slab with a retarder rolled on one half, and a water jet washing the other half to expose the stone aggregate Exposed aggregate finish Exposed (washed) aggregate gives slip-resistant, decorative paving, walls and panels, and a rough key at construction joints. A surface retarder stops the top layer from setting so it can be washed off to reveal the stone. 7 steps
