摘要

Ready mixed concrete (RMC) placing is an important operation on construction projects in many countries. This is particularly true as in Egypt high- rise buildings construction increased in the building industry, many of these buildings are still constructed using the traditional method of in-site concrete placing. Concrete must be batched remotely and delivered to sites by truck mixers Therefore, the production rate of Pouring Ready Mixed Concrete (PRMC) could be considered as great importance to improve the productivity of the whole construction industry in Egypt. The aim of this paper is to build a new regression model using correlation analysis method for predicting the production rate of PRMC using tower cranes. The model building was based on a close observation of 418 pours cycles from ten different construction building sites for the pouring concrete in columns, slabs, and beams, each from the beginning to end operation. In addition, it studied the factors affecting the production rate of PRMC using tower cranes. The results of the model implementation in concrete placing for columns, slabs and beams presented an average percentage error value of 2.8197%.
