Machine Learning Prediction Models to Evaluate the Strength of Recycled Aggregate Concrete

Materials, 2022
Compressive and flexural strength are the crucial properties of a material. The strength of recycled aggregate concrete (RAC) is comparatively lower than that of natural aggregate concrete.

Sustainability assessment of recycled aggregate concrete structures: A critical view on the current state‐of‐knowledge and practice

Structural Concrete, 2023
The environmental impacts of activities such as raw material extraction, construction of infrastructure, and demolition, place construction as one of the sectors that exert the highest pressures on the environment, society, and economy. Some of the major

Mechanical properties and microstructure of nano-SiO2 and basalt-fiber-reinforced recycled aggregate concrete

Nanotechnology Reviews, 2022
In this study, nano-SiO2 (NS) and basalt fiber (BF) were used to improve the quality of recycled aggregate concrete (RAC). The crushing value, water absorption, and apparent density of NS-modified recycled coarse aggregate (RA) were determined, and the ...

Impact Properties of Recycled Aggregate Concrete with Nanosilica Modification

Advances in Civil Engineering, 2020
The optimal soaking time and nanosilica concentration were chosen by the physical properties of the nanosilica-modified recycled aggregate. Recycled aggregate concrete (RAC) and nanosilica recycled aggregate concrete (SRAC) were fabricated by using ...

Comparison of Prediction Models Based on Machine Learning for the Compressive Strength Estimation of Recycled Aggregate Concrete

Materials, 2022
Numerous tests are used to determine the performance of concrete, but compressive strength (CS) is usually regarded as the most important. The recycled aggregate concrete (RAC) exhibits lower CS compared to natural aggregate concrete.

Cost-benefit analysis of the production of ready-mixed high-performance concrete made with recycled concrete aggregate: A case study in Thailand

Heliyon, 2020
In the current green concrete structures, recycled concrete aggregate is used as recycled concrete waste. In this process, concrete waste is collected and crushed using a recycling procedure in order to produce crushed concrete which is then used in ...

Study the effect of vibration mixing on the performances of full replacement recycled aggregate concrete [PDF]

E3S Web of Conferences, 2021
It is an urgent problem that the construction solid waste is difficult to be treated, and its recycling provides a way for its treatment. The quality of construction solid waste recycled aggregate is lower than that of natural aggregate, which limits its

Carbonation of concrete with construction and demolition waste based recycled aggregates and cement with recycled content [PDF]

, 2020
Durability is a major concern in concrete (particularly recycled concrete) structures exposed to carbonation-induced corrosion, given the social, economic, environmental and safety implications involved.
