We are happy to announce that version 1. A new study about materials science dedicated to concrete has just been released!

The common method of expressing the proportions of ingredients of a concrete mix is in the terms of parts or ratios of cement, fine and coarse aggregates. For e. The proportions are either by volume or by mass. The water-cement ratio is usually expressed in mass.

Factors to be considered for mix design. Determine the mean target strength f t from the specified characteristic compressive strength at day f ck and the level of quality control. Obtain the water cement ratio for the desired mean target using the emperical relationship between compressive strength and water cement ratio so chosen is checked against the limiting water cement ratio. The water cement ratio so chosen is checked against the limiting water cement ratio for the requirements of durability given in table and adopts the lower of the two values.

Estimate the amount of entrapped air for maximum nominal size of the aggregate from the table. Select the water content, for the required workability and maximum size of aggregates for aggregates in saturated surface dry condition from table. Determine the percentage of fine aggregate in total aggregate by absolute volume from table for the concrete using crushed coarse aggregate.

Adjust the values of water content and percentage of sand as provided in the table for any difference in workability, water cement ratio, grading of fine aggregate and for rounded aggregate the values are given in table.

A factor was considered to have significant effect on the compressive strength if value was found to be less than 0. Table 5 shows that the and have significant effects on compressive strength as their levels of significance, values, are less than 0.

Therefore, these two significant variables should be considered for obtaining the regression model for compressive strength,. The polynomial regression model obtained for compressive strength using the data presented in Table 4 is presented as follows: where is the day compressive strength in MPa. The upper and lower bounds of each of the three variables are given in Table 1.

The developed compressive strength model was utilized for optimization of concrete mixture design corresponding to the following options i. This indicates that, at the same optimum values of and , the compressive strength is more at lower cementitious materials content i.

From Table 6 , the concrete mixture having a maximum compressive strength of A simplified step-by-step approach is proposed for optimizing the concrete mixture design based on the analysis of the data obtained through a statistically planned experimental program.

The proposed approach consists of five steps, as follows: i specification of the characteristic performance of concrete, ii selection of the levels of key mix design factors, iii experimental work considering trial mixtures using full factorial experiment design for generating data to obtain statistical model for optimization, iv statistical analysis of experimental data and fitting of the strength model, and v optimization of mixture proportions using the fitted strength model.

Concrete Mix Design. The process of selecting suitable ingredients of concrete and determining their relative amounts with the objective doncrete producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design. The proportioning of ingredient of concrete is governed by the required performance of concrete in 2 miz, namely the plastic and the hardened states. If the indla concrete is not workable, it cannot be properly placed and compacted. Page maker software free download full version concrete mix design software india free download of workability, therefore, becomes of vital concrete mix design software india free download. The compressive strength of hardened concrete which is generally considered to be an index of its other properties, depends upon many factors, e. The cost of concrete is made up of the cost of materials, plant concrete mix design software india free download labour. The variations in the cost of materials arise from the fact that the cement is softwrae times costly than the aggregate, thus the aim is to produce as lean a mix as possible. From technical point of view the rich mixes may lead to high shrinkage and cracking in the structural concrete, and to evolution of high heat of hydration in mass concrete which concrete mix design software india free download cause cracking. The actual cost of concrete is related to the cost of materials required for producing a minimum mean strength called characteristic strength that is specified by the designer of the structure. This depends on the quality control measures, but there is no doubt that the quality softwre adds to the cost of concrete. The extent of quality control is often an economic compromise, and depends on the size and type of job. The cost of labour depends on the workability of mix, indua.
