Creep Definition. Concrete creep is defined as: deformation of structure under sustained load. Basically, long term pressure or stress on concrete can make it change shape. This deformation usually occurs in the direction the force is being applied. Like a concrete column getting more compressed, or a beam bending.
Concrete strength gain - Concrete strength increase with age as moisture and a favorable temperature is present for hydration of cement. An experimental investigation was conducted by "Cement, Concrete & Aggregates Australia" (CCAA) and the same was published in their data sheet on "Curing of Concrete," which has been included in this article for reference.
concrete will absorb water from the batch water resulting in a lower slump. This water that will be absorbed by dry aggregates needs to be accounted for by adding additional water to the mixture. Therefore the aggregate moisture has to be measured and the amount of batch water adjusted accordingly.
Ordinary concrete is nominal mix. Controlled concrete is designed mix supposed to be done using batching plants. Controlled concrete is by weight & designed. Ordinary concrete is by volume & it is used in P.C.C. In controlled mix quality, durability & strength is ...
Most batch plant operators work BY BRUCE A. SUPRENANT Slump adjustment is a fact of life for concrete contractors, but they should follow these guidelines for its use Variations in slump between trucks can be the result of many factors. Long delivery, waiting, and unloading times, for example, can decrease slump. Add water, if necessary, in

Volume Batching : The materials of concrete are to be taken by Volume as the proporion. Weight Batching : The materials of concrete are to be taken by Weight as the proporion. Weight batching is prefered as we are getting better result than Volume batching.

Batching by volume achieved by using a constructed gauge boxes (Farmas) for proportioning the materials according to various mix proportions and based on the quantity of material needed per batch. In small works gamellas are also used for batching. But it is not recommended for batching of concrete. 03

Oct 14, 2015 · R M C ( Ready Mix Concrete ) Ready – mix concrete is type of concrete that is manufactured in a factory or batching plant , according to design and then delivered to a work site , by transit truck. RMC is bought and sold by volume. The truck carries a mix in a revolving chamber which like the concrete mixer .
specification for structural concrete This is the second of three articles discussing ACI 301-10, “Specifications for Structural Concrete.” The first article summarized the major modifications to ACI 301, including additional chapters on industrial floor slabs, tilt-up construction, precast concrete, and architectural precast concrete.
high quality concrete producing processes, choosing an appropriate batching method plays an essential role. There are two common methods to be volume batching and weigh batching. Generally speaking, volume batching is not a preferred way the concrete producer may choose for proportioning the raw materials including Portland cement, aggregates

mixed concrete is sold on the basis of the volume of fresh, unhardened concrete-in cubic yards (yd 3) or cu-bic meters (m3) as discharged from a truck mixer. The basis for calculating the volume is described in the ASTM C 94, Specification for Ready Mixed Con-crete. The volume of freshly mixed and unhardened concrete in a given batch is ...

The volume increase of fine aggregate due to presence of moisture content is known as bulking. Fine sand bulks more as compared to coarse sand. Extremely fine sand particularly the manufactured fine aggregate bulks as much as about 40%. Note: Fine aggregate do not show any bulking when it is absolutely dry or completely saturated. ...
If volume batching has to be adopted, the volume measures should be checked frequently for the weight volume ratio. Mixer’s performance also should be checked to the requirements of the relevant standards. Concrete should be mixed for the stipulated time as under mixing and over mixing both affect the compressive strength of concrete and ...
For very small projects, such as setting a mailbox post or doing repairs, you may want to purchase a packaged concrete mix. Such a mix combines cement, sand, and gravel in the correct mixing ratios and requires only the addition of water to create fresh concrete.
Methods of Batching Concrete 1. Volume Batching. In volume batching, materials are measured on the basis of volume. It is less precise method of batching; Measurement boxes or gauge boxes of known volume are used to measure materials. Cement is taken in the form of bags, where volume of one bag of cement (50 kg) is taken as 35 liters.

The absolute volume of a concrete mix can be determined if the weight and bulk specific gravity of the components are known. For a concrete mix with 90-lbs of coarse aggregate with Gs = 2.65, 60-lbs of fine aggregate with Gs = 2.63, 25-lbs of cement, and 12-lbs of water the absolute volume is computed as follows:
There are two ways of batching of aggregates for concrete mixes: by volume or by weight. The latter method is the most common since it "eliminates errors due to variations contained in a specific volume" (Murdock, 130).

What Is Volume Batching of Concrete? Batching of concrete means measuring different ingredients of concrete (i.e. cement, sand, coarse aggregate and water) before mixing it. When this measurement is done on the basis of volume, we call it Volume Batching.
M 20 is identified as the concrete grade in which, M denotes the Mix and 20 denotes the compressive strength of concrete cube after 28 days of curing in N/mm 2. There are various grades of concrete that can be used like M10, M15, M20, M25, M30, etc. Also Read: What do you mean by Batching of Concrete?
