Big budget for mass concrete raft foundation volume 24,603 m3, fc35 MPa, wctitious ratio 0,4, fly ash 15%, fresh concrete 320C, concrete using ice water. The purpose of this study, to find alternative concrete, by analyzing the Value Engineering analysis ... see more

Big budget for mass concrete raft foundation volume 24,603 m3, fc35 MPa, wctitious ratio 0,4, fly ash 15%, fresh concrete 320C, concrete using ice water. The purpose of this study, to find alternative concrete, by analyzing the Value Engineering analysis ... see more

This article presents the assessment of early-age cracking risk in a mass concrete footing which is cast under different construction conditions. A finite element (FE) model was developed for predicting temperature, thermal stress, and cracking potential ... see more

Predicting adiabatic temperature rise is essentially useful for investigating thermal cracking potential especially in early stage of mass concrete.  Existing prediction methods and models have some problems such as constant thermal properties are mo... see more

A method for estimating mix proportion of hardened OPC concrete is proposed in this study. A set of mass balance equations was formed to calculate content of concrete compositions including cement, water, sand, and coarse aggregate. The degree of hydratio... see more

As the size of modern infrastructure increases, novelties related to mass concrete mixtures including supplementary cementitious materials (SCMs) become critical. The effects of binary and ternary cement replacement mixtures including metakaolin, silica f... see more

In this paper, we present an experimental study and statistical modeling of High-Performance Concrete subjected to high temperatures. The main objective of this study is to examine the effect of concrete age subjected to high temperature cycles (ranging f... see more

The purpose of this study is to develop a low cost, locally produced concrete mixture with optimum marble content. The resulting mixture would have enhanced strength properties compared to the non-marble reference concrete, and improved radiation shieldin... see more

This work presents how the Estes model was applied for studying and simulating labor learning rates in a specific construction task. The basic theory of thismodel is presented, and then applied for concrete block layering labor productivity data from mass... see more
