A strength-based mix design method for recycled aggregate concrete
This paper puts forward a strength-based mix design method for recycled aggregate concrete using a modified empirical formula. A total of 30 mixes, the amount of cement varies from 300 kg/m 3 to 500 kg/m 3 and the proportion of recycled coarse aggregate ranges from 0% to 100%, were prepared for the regression analysis of This study proposes a new mix design method for C30 recycled concrete using recycled aggregate crushed from different strength source concrete (SC). The dosages of cement, water, sand, and coarse recycled concrete aggregate (CRCA) are the same as the corresponding components in natural concrete, but the CRCA should be pre New Mix Design Method for Recycled Concrete Using Mixed Source Concrete

A mix design method for self-compacting recycled aggregate concrete
Therefore, a novel method is proposed for designing self-compacting recycled aggregate concrete (SCRAC) mix. The method is developed by target slump-flow and target compressive strength, avoiding tedious adjustments and laboratory re-testing at the concrete level.This paper proposes a conceptual formulation for predicting and controlling the compressive strength of Recycled Aggregate Concrete (RAC) mixtures, by explicitly taking into account the specific features of Recycled Concrete Aggregates (RCAs).A novel mix design methodology for Recycled Aggregate Concrete

Mix Design and Properties of Recycled Aggregate Concretes
At fresh state, the mix design of concrete with recycled aggregates requires an additional quantity of water to obtain a similar workability as a concrete formulated with natural aggregates (Hansen and Boegh 1986 ). Such a modification may obviously affect the mechanical characteristics of recycled aggregates concrete.Request PDF Mix design for recycled aggregate pervious concrete based on response surface methodology This paper demonstrates that RSM can be used to design the mix proportion of...Mix design for recycled aggregate pervious concrete

A novel mix design methodology for Recycled Aggregate Concrete
Improving the performance of the interface between old mortar and recycled coarse aggregate (RCA) is a hot topic and important to enhance the properties of recycled aggregate concrete (RAC). In this paper, the RCA was soaked by nano-SiO2(NS-RCA) then the water absorption and crushing index of NS-RCA were investigated.The undesirable properties of conventional recycled fine aggregate (RFA) often limit its application in the construction industry. To overcome this challenge, a method for preparing completely recycled fine aggregate (CRFA), which crushes all concrete waste only into fine aggregate, was proposed. The obtained CRFA had high apparent density, Concrete Mix Design for Completely Recycled Fine Aggregate by

Mix design for recycled aggregate pervious concrete based
The goal of this paper is to obtain admixture dosage and aggregate gradation in the mix design of recycled aggregate pervious concrete. The final purpose is to facilitate the use of recycled aggregate in permeable concrete, broaden the application field of RSM in concrete mix design, and help reduce the production cost of concrete and New Mix Design Method for Recycled Concrete Using Mixed Source Concrete Coarse Aggregate Xiaomeng Ding1 Jianli Hao2 Zhongfan Chen1 Jianan Qi1 Meloni Marco1 Received: 30 October 2019 / Accepted: 16 April 2020 / Published online: 2 May 2020 © Springer Nature B.V. 2020 AbstractNew Mix Design Method for Recycled Concrete Using
