Conversely, it can be used to obtain the concrete mix proportions that can be afforded by a specified amount of money. The model values were approximately equal to estimated values. The use of the optimisation model eliminated the arbitrary choice of concrete design mixes and its associated ...
Powerful and efficient: The electric motor ensures reliable performance, making it easy to mix cement and concrete. Wire rope hoisting: The wire rope hoisting system allows for easy transportation and positioning of the mixer. Mobile and portable: With its compact design, this ...
Transit mixers form an important component of the facility and are included in the calculations. A fleet size for transit mixers has been assumed for this purpose. The life cycle cost has been calculated for the system of the ready mix concrete plant and transit mixers. 展开 ...
Design:With the many design options concrete offers, this is where the most variance can occur. From simply including an integral color in the mix to a complicated stamped and stained design, the parameters are really up to you and what you want to spend. (See pictures ofdecorative concrete...
Mexico:The Mexican Ready-Mix Concrete Industry Association (AMIC) says that European natural gas shortages and disruptions to the supply of oil, chemicals and other goods as a result of the conflict in Ukraine may cause a rise in the cost of global cement ...

There are several workability test methods proposed to evaluate workability of self-consolidating concrete (SCC). Most of these methods are not standard, and their reliability is still under question. In this study, a comprehensive experimental program and statistical analysis were performed to evaluate...
How did Ian and his team come to the conclusion that the return on equity (ROE) application has a TCO of $390,000 per year but a poor strategic fit of three? The answer in brief is:Facts and opinions. A concrete indicator such as TCO can mostly be calculated on the basis of facts...
Steel fibre reinforced concrete (SFRC) is a construction material investigated for more than 40 years including for pavement applications. A number of studies have demonstrated the technical merits of SFRC pavements over conventional concrete pavements; however little work has been carried out on the ...
If the concrete mixer truck cannot get into the site to pour it, the mix must be moved by wheelbarrow, which will add to the cost of labor. A deeper base for the concrete patio may be necessary due to its location. Soggy or wet locations might also require installation of drainage. ...
