Moisture Control in Concrete Production | Agg-Net

There are two distinct types of concrete: ready-mixed and precast. Ready-mixed concrete is typically manufactured in a batching plant and delivered to site by truckmixers for use in its freshly mixed state. Precast concrete is used to make individual cast concrete elements that typically form part …

What are the Correct Concrete Mixing Ratios - Ratio Chart

When making your own concrete it's important to use the correct concrete mixing ratios to produce a strong, durable concrete mix. Some basic mixing ratios for concrete are 1:2:3, 1:3:3, 1:2:4. These mixing ratios are based on the proportions of cement : sand : stone in that order. The ratio you use will depend on what psi strength you need.

THE BLUE CIRCLE BUILDERS' GUIDE TO CEMENT

Accurate proportioning (or batching) of materials and thorough mixing are essential for making good quality concrete. Either method of batching, by weight or by volume, may be used. When using the batching by volume method, it is important that the materials are measured with the aid of a batch gauge box. A batch box has four sides and no bottom.

RENDER for Small Projects

This is particularly important with pre-mixed render products as the amount of cement in the mix is usually unknown. Pre-bagged or dry-mix products For small projects and even some larger ones, the simplest way to make render suitable for most applications is to purchase a pre-bagged render mix from a local hardware supplier.

Concrete-Based and Mixed Waste Aggregates in Rendering Mortars

This paper presents a study of incorporation of two types of construction and demolition waste (CDW) in rendering mortars, as aggregates at 0%, 20%, 50% and (by volume). Recycled concrete aggregate (RCA) and mixed recycled aggregate (MRA) were used. The former is mainly composed of cementitious waste and the latter consists of a mixture of non-segregated wastes.

Mortar and Concrete Mixes - EzineArticles

For concrete steps, make the mix maybe a bit stronger, 1:4. If you're laying bricks, it's 1:4 (soft sand). For rendering, use 1:4 (2 fine-washed and 2 soft sand). If you're doing a floor screed, it should be 1:3 (sharp sand). Additives are available for many tasks if required. Plasticiser is excellent in mortar, but be careful not to use too much.
