Waste aggregate concrete properties using waste tiles as coarse aggregate and modified with PC superplasticizer

Open Engineering, 2022
Concrete is the most popular construction material and has a relatively high compressive strength and it does not crack under its own weight, but its tensile strength is much lower compared to its compressive strength.

Sonicating polycarboxylate-based superplasticizer for application in cementitious matrix

Revista IBRACON de Estruturas e Materiais, 2022
Sonication is widely used for nanomaterials dispersion in cementitious matrices. Polycarboxylate-based superplasticizer (SP) admixtures are usually incorporated in the aqueous nanomaterials suspension before sonication to improve the dispersion of these ...

A PROPOSAL FOR RATIONALIZATION OF THE SUPERPLASTICIZATION PROCESS OF SUPERPLASTICIZED CONCRETE

Doboku Gakkai Ronbunshu, 1986
This study concerns the development of an efficient superplasticizing apparatus capable of simultaneously measuring, introducing, and mixing superplasticizer with the aims of rationalizing and systematizing the superplasticization process which poses the greatest obstacle to the wide use of superplasticized concrete.

Prediction of compressive strength of cementitious grouts for semi-flexible pavement application using machine learning approach

Case Studies in Construction Materials, 2023
This study involves the preparation of cement grout samples by varying proportions of superplasticizer (SP) and water-cement (w/c) ratio (0.25–0.45) which were tested for computing flow value and 1-day, 7-day, and 28-day compressive strength.
