ABSTRACT:
A method of mixing concrete and containers for providing predetermined quantities of cement and aggregate to be transported to a site for on site mixing of concrete. The containers have two compartments which are self closing due to the weight of the contents, one compartment containing cement and the other aggregate. When placed on a ring-like support the compartments move relatively to release their contents. The hopper of the concrete mixer has a ring-like support to open the containers and has a water spray curtain to prevent the fine cement powder to be taken away by the wind, with the water spray providing the correct amount of water for the concrete.
