CONNECTIONS FOR PRECAST FLOOR SLABS

The Constructor

This tie prevents the beam and the slab separating during the in-situ concrete screeding operation. Finally, in-situ concrete is poured. First, a rubber bearing is placed at the support point. When the slab is in position, a welded connection is made. Reinforcement is placed onto the top of the slab.

Sugar in Concrete | Effect of Sugar on Concrete Strength | Sugar as a Concrete Surface Retarder | Addition of Sugar in Concrete Results in Setting Time

CivilJungle

Sugar in Concrete: Cement and Concrete are the foremost paramount engineering materials. Tyrannical weather conditions play indispensable roles on the traits of concrete. Continuous change in weather conditions results in a change of initial setting time of concrete. Concrete gets brawny as it grows older over time.

Fly Ash in Concrete

Construction Cost Estimating

Pozzolanic admixtures or mineral admixtures are those materials which in itself don't have any cementitious characteristics however show cementitious properties in their finely separated structure when joined with lime, for example Calcium Hydroxide (Ca (OH)2) with dampness. Consequently, it upgrades the solidness properties of concrete.
