(PDF) Mix Design of High-performance Concrete
A mix design procedure for high-performance concrete mixes has been presented in this paper. Since rheological parameters and compressive strength are fundamental properties of concrete in twoVarious design methods of GPC prepared with various types of slag and FA have been proposed. The following conclusions can be drawn based on review and discuss on above GPC mixture proportioning methods: (1) The most used method is target strength method. AL/B and W/B are correlated to strength and workability of GPC, which A review on mixture design methods for geopolymer concrete

A novel mix design methodology for Recycled Aggregate Concrete
Section snippets Aggregates. According to ASTM C33 [35], three different size ranges were considered for aggregates: sand (nominal diameter smaller than 4.75 mm), coarse class 1 (C1, nominal diameter ranging between 4.75 mm and 9.5 mm) and coarse class 2 (C2, nominal diameter ranging between 9.5 and 19 mm). It is worth highlighting This paper deals with the investigation of an experimental mix design method and production of recycled concrete incorporating fine recycled aggregate (FRA) from mixed construction and demolition waste. During the experimental mix design process the recycled concrete workability was measured using Graff's flow table instead of using Evaluation of an experimental mix proportion study and

Due to the specific gravity of recycled brick aggregate (RBA) is less than that of natural aggregate (NA), the traditional mix proportion design of concrete can not be used. The purpose of this study is to propose a new mix proportion design method, which is suitable for recycled brick aggregate concrete (RBAC) or lightweight aggregate concrete.The use of recycled aggregate concrete (RAC) is undoubtedly on the increase and further research is required for more appropriate mix design methods. This paper presents the result of investigations into the mix design of RAC. The study examined experimentally two conventional and one unconventional mix design methods.

Recycled aggregate concretes A state-of-the-art from the
Pre-treatment of recycled aggregates and mixing processing. One of the difficulties in the application of recycled aggregate concrete in practice is the control of recycled aggregate’s water content. A high water absorption and heterogeneity of recycled aggregate causes difficulties to determine the accurate water from the formulas [32], [33].The strength reduction in CPH and CP is about 40% and 50% with respect to CP 1. The water-to-cement ratio is high for the mixes with PCM, leading to a reduction in strength compared to CP 1. Also, the use of low-strength particles, namely PCM, in the matrix effectively brings down the strength of PCM-admixed concrete.Mix Proportioning PCM Concrete for Workability and Performance

Investigating Trends and Costs Associated with Designing
Concrete mixes can be designed using many methods such as the British method (DOE) and the American method (ACI). It is beneficial to compare different mixes and examine their performances and the associated costs. However, designing and comparing concrete mixes by hand can be time consuming and is prone to errors. Use of recycled concrete aggregate in construction industry has brought a revolutionary change in enhancing sustainability, improving economy, implementing waste management rules, conserving non-renewable energy resources.
