2018-3-27 Properties of Concrete. Some of the main and unique properties of concrete are its workability and water-cement ratios. 1. Workability. The ability of fresh mix concrete to fill the mold with proper vibration and poring method is workability. Workability depends on the water content, aggregate, binding materials, chemicals in concrete. ...
2012-11-7 ACI METHOD OF PROPORTIONING CONCRETE MIXES The ACI Standard 211.1 is a “Recommended Practice for Selecting Proportions for Concrete”. The procedure is as follows: Step 1. Choice of slump Step 2. Choice of maximum size of aggregate Step 3. Estimation of mixing water and air content Step 4. Selection of water/cement ratio Step 5. ...

Methods of Proportioning Concrete Arbitrary Method of Proportioning Concrete The general expression for the proportions of cement, sand and coarse aggregate is 1 : n : 2n by volume. 1 : 1 : 2 and 1 : 1.2 : 2.4 for very high strength. 1 : 1.5 : 3 and 1 : 2 : 4 for normal works. 1 : 3 : 6 and 1 : 4 : 8 for foundations and mass concrete works. ...
2021-8-20 Determining the proportion of cement, fine aggregate, and coarse aggregate for concrete mix is known as the proportioning of concrete. The principle of proportioning aggregate is that the smaller particle will fill up the voids between large particles. A well proportioned concrete mix requires a minimum amount of cement per unit volume. ...
2011-5-16 produced by Minergy. Crushed glass aggregate from the Minergy Pilot Plant produced from Fox River sediments was used in the batching and testing. This glass aggregate was incorporated into an air entrained concrete mix with ¾” maximum nominal aggregate size that is typical of a concrete mix that is commonly used for commercial applications. The purpose of this testing and evaluation was to compare the physical properties of the concrete mixture containing the glass aggregate component to a similar mix composed exclusively of locally available, naturally occurring aggregates. Strength, water demand and workability of the mixture containing the glass aggregate were compared to the traditional concrete ...
With a workable concrete mix, slump test and making concrete cubes was also done. Slump test When making the slump test, the base of the slump cone was put on a flat surface. The cone was then filled with wet concrete in three layers. Each layer was tempered 25 times with a standard 16mm (diameter steel rod, rounded at the end). ...
