[email protected]This method of concrete batching may not be economical.It can be only used for unimportant concrete or for small concrete works.How volume batching is done in field? before batching concrete ingredients in terms of volume, we need to know two things.What is the relative proportion of concrete ingredients in terms of volume?.
Calculation of cement, sand quantity for plastering how much cement, sand and water is required for 12mm thick plastering? plastering is done on the walls to remove surface imperfections, maintain line level and alignment.In addition to that it also acts as a protective surface for external walls.Cement plaster, gypsum plaster and lime plaster [].

Read Morecreep and shrinkage of concrete are two physical properties of concrete.The creep of concrete, which originates from the calcium silicate hydrates (c-s-h) in the hardened portland cement paste (which is the binder of mineral aggregates), is fundamentally different from the creep of metals and polymers.Unlike the creep of metals, it occurs at all stress levels and, within the service stress.

Read Morethe current practices of the construction of cement concrete road for highways in india require a layer of dry lean concrete (dlc) as a base course over which pavement quality concrete slabs rest.It is one of the common and popular cement treated sub-base/base for concrete pavements.
Read Morefor calculation purposes, lets assume that the area that needs to be plastered is 100 sqft (10 ft x 10 ft wall) and a plaster of mix ratio 1:4 (cement:sand) is used.We shall use dlbd method (dry loose bulk density) in determining the ratios.This is the most accurate method as it accounts for the variations in the loose bulk density.

Read MoreShotcrete is not a special product of concrete and it is not a special method of placing concrete.In dry-mix method the dry cementitious mixture is blown through a hose to the nozzle, where the water is injected immediately.The dry-mix method appears to be better for low volume placements.
Read MoreCompressive strength.The compressive strength of any material is defined as the resistance to failure under the action of compressive forces.Especially for concrete, compressive strength is an important parameter to determine the performance of the material during service conditions.

Read Moreconcrete subjected to a dry atmosphere will, in most cases, have a greater drying shrinkage than if subjected to an alternative wetting and drying.Lower temperatures generally produce a decrease in drying shrinkage because of higher humidity and slower evaporation.
Read MoreThe process of silo selection starts with a series of questions that require answers before proceeding.This is one of the main problems witnessed in todays dry bulk storage market.Tank and silo selection many times is based on a preferred construction type in lieu of stored material.
Read MoreThe concrete cures, getting harder and harder, while excess water gradually evaporates from the material.Ideally, evaporation is controlled until the initial curing phase has passed, then the excess moisture is allowed to evaporate into the air so that the concrete can fully cure and dry.
