Factors affecting concrete are largely related to site work and are often beyond the control of the ready mix supplier.
Prepare the Ground and Formwork First
In preparation for the arrival of the ready mix concrete Cheltenham lorry, ensure that the formwork has been adequately braced and that any joints within the formwork have been sealed to prevent a blowout. Lay a sub-base to an adequate depth for the job in hand (typically in the region of 100mm to 150mm for a domestic slab). Ensure that the reinforcement mesh or rebar has been laid in the correct locations.
Time the Pour Carefully
Most ready mixes are designed to be used within 90 minutes of batching, and it’s essential that the site is able to pour the Concrete Cheltenham in a timely manner. Take into account local traffic, as well as the site access, to ensure that there are enough people to pour the concrete when it arrives.
Pour and Spread Without Delay
Work the concrete in layers, use a rake or screed board to guide the concrete into the corners and other hard to reach areas of the formwork. Attempting to drag the concrete from a distance can cause it to segregate.
Compact With a Poker Vibrator
Air can be left in the concrete when tamping alone. However, the use of a poker vibrator will aid in removing any voids within the concrete to produce a solid and strong concrete mass. Guidance for the safe handling of concrete on construction sites and skin protection against wet cement can be found on the HSE website.
Finish and Then Cure
Screed and float the finished surface. Cover the slab with polythene sheeting or a suitable curing membrane to retain moisture for at least 3 days and preferably 7 days or more.
