Properties of pavement quality concrete and dry lean concrete with copper slag as fine aggregate ... and dry lean concrete (DLC) mixes. A control mix for PQC was prepared with 400 kg/m 3 of ordinary Portland cement (OPC) and water–cement (w–c) ratio of 0.40. Other concrete mixtures were then prepared by substituting 20%, 40%, 60%, 80% and ...
Both place concrete by pneumatically projecting the material from a hose. The difference is when water is added to the material. In a wet-mix application, all materials – including cement, aggregate, ad-mixture and water – are mixed together before being pumped through a hose and pneumatically projected.
Cement content The strength of concrete increases with increasing the cement for a fixed water content, But also a stiff lean-mix can have a higher strength then a standard wet mix if the water content of the lean-mix is low ...

Chapter 10 Mix Design The purpose of a mix design is to group the aggregates in different proportions to achieve the desired strength. The components of a mix are proportioned so that the resulting concrete has adequate strength, proper workability for placing, and low cost. Low cost is achieved by using the minimum amount of cement required to ...
Jan 28, 2019 · Lean concrete and flowable concrete are terms used to describe low-grade concrete slurry that is used in a variety of construction projects. In some ways the two terms are interchangeable, both describing concrete made with lesser ingredients, but there are some differences in how the two are used.
These are the actual concrete mix ratios for 3000, 3500, 4000, and 4500 psi concrete that I use to pour concrete floors, patios, pool decks and more. I'll show you the actual concrete batch plant ticket with the cement, sand, and aggregate break downs for the yards we used.
5.3 MIX DESIGN METHODS 5.3.1 CONCRETE MIX DESIGN 1. Scope. This method covers the procedure for designing concrete mixes and is based on the absolute volumes of the various components of the mix, i.e.: the absolute volumes of cement (plain, blended or fly ash modified), aggregate, water and air in one cubic yard of concrete. 2. Procedure. 2.1.
Design mix method :- In this method, materials are proportioned based on the procedure and rules given in IS 456 (2000) and IS 10262) code In this method, cement, sand and aggregates are always batched in terms of weight, and concrete can be designed for different environmental conditions and different needs.
