Controlling the quality of the concrete product during the manufacturing phase depends mainly on reducing the weighting errors. Integrating computer in industrial manufacturing control ensures continuous …
Recently, an experimental study on steel–concrete composite beams strengthened by PUR systems with CFRP plates were carried out [31]. In this work, as a follow-up study, a refined 3D FE model has been developed and verified using test findings. Furthermore, a parametric study is conducted by the validated FE models to …
Corrosive media, such as sulfates, generally exist in the service environments of concrete structures that have been in service, and the porous structure of concrete allows the easy ingress of SO4 2−; sulfate attack triggers a chemical reaction that causes the internal volume of the concrete to expand, resulting in cracking of the concrete and …
1. Introduction. Large-scale additive manufacturing with cementitious materials is commonly referred to as 3D Concrete (3DCP). 3DCP has attracted interests from the construction industry because of its potential for greater geometric freedom, less reliance on formwork and labour, and productivity improvement [1, …
The total size of the concrete blocks (i.e., width, height, length) is determined after performing a thermo-economic parametric study for different concrete block sizes (i.e., in terms of number of tubes and number of concrete blocks) in Section 4.3.1.

Jacob-Vaillancourt and Sorelli (2018) performed an experimental study on the properties of concrete containing plastic wastes (up to 50%) as a replacement of natural aggregates. Based on the obtained experimental results, a conclusion can be made that the designed lightweight concretes containing plastic waste aggregates present a …
This study aims to determine the financial feasibility and business opportunities on batching plant investment of ready mix concrete at Sigli-Banda Aceh highway project.
