There are two ways of mixing the cement, sand, aggregates and water to make concrete: by hand or with the help of a machine. Hand mixing is usually reserved for a small project, and it takes a lot of work to get right.
Consistency is the main advantage of choosing concrete ready mix over on-site mixes, followed by ease of use. Having the cement and aggregate mixed at the plant ensures that every batch of concrete has the same composition.
Ready mix concrete is a combination of cement, sand, aggregates and water mixed either in part or entirely at a central plant and delivered in batches to construction sites. Each batch is mixed according to the contractor’s specifications
While ready mixed concrete pumping is a fast solution, winter adds its own challenges and these are the things you should be aware of. Winter is almost upon us and, as everyone can tell you, winter is not the time of the year when people usually bring out the sacks of ready mixed concrete and start doing construction work. At least not major work, such as putting up outside walls or building a roof. Winter is traditionally the time to do indoor work, though anything that requires drying or dry weather is best left until spring or even summer.
