During the first week of October our Managing Director, J. YUGPK is the leader in the region for cement manufacturing, with a state-of-the-art factory with a[….. 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.
