A Statistical Approach to Optimizing Concrete Mixture Design

A step-by-step statistical approach is proposed to obtain optimum proportioning of concrete mixtures using the data obtained through a statistically planned experimental program. The utility of the proposed approach for optimizing the design of concrete mixture is illustrated considering a typical case in which trial mixtures were considered according to a full factorial experiment design ...

How to Properly Mix Concrete (DIY) | Family Handyman

Whether you hand mix concrete in a plastic tub, homemade mixing tub or wheelbarrow, the technique is the same to find the right concrete mix ratio. However, it's easier to move and dump concrete that's mixed in a wheelbarrow. For larger jobs, you could rent a mixer ($35 per day), but it may be more economical to simply order ready-mix concrete.

When to Use Hot Weather Concreting Methods - The Concrete Network

Retarding admixtures are another tool to control concrete in warm weather. Retarder can be added at the plant or on the job site to delay concrete setting time, which can be very quick when the concrete is hot. Retarders give you extra time but they also give the concrete more time to dry out, so curing is critical.
