Effect of poly car boxy late admixtures on portland cement paste setting and rheological behaviour
Materiales de Construccion, 2005 The objective of the work was to determine the effects of polycarboxilated-type admixture on the setting times and the rheological properties of different types of cements including CEM I 42.5 R, CEM Il/B-V 42.5 N and CEM III/B 32.5 N, defined according ...

Global Challenges, EarlyView.Open porous geopolymer‐based cordierite materials are produced due to the porous structure, temperature resistance, easy and low cost applications of geopolymer. For the composition of cordierite, waste boron clay, metakaolin, fly ash and magnesium carbonate are used, while keeping the geopolymerization temperature constant, sodium silicate, sodium ...

Influence of superplasticizers on the evolution of ultrasonic P-wave velocity through cement pastes at early age [PDF]
, 2013 The paper discusses a possibility of using an ultrasonic wave transmission method to study the influence of superplasticizers on the formation of structure of cement pastes at early ages. When compared to mixtures without additives, lower P-wave velocity

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT The advancement of artificial intelligence (AI) in material design and engineering has led to significant improvements in predictive modeling of material properties. However, the lack of interpretability in machine learning (ML)‐based material informatics presents a major barrier to its practical adoption.

Bond of Reinforcement to Superplasticized Concrete [PDF]
ACI Journal Proceedings, 1986 The effects of superplasticizers on concrete-steel bond strength were studied. Key variables were degree of consolidation; concrete slump, both with and without a superplasticizer; concrete temperature; and bar position. No. 8 deformed reinforcing bars were used with a 2-in (51mm) cover and a 10 in. (254 mm) bonded length. Concrete slumps ranged from 1

Compatibility Assessment of Commercial Cements with superplasticizers [PDF]
E3S Web of Conferences, 2020 In the present study, compatibility assessment of commercially available cements (OPC and PPC) and SNF & PCE based super plasticizers are made by evaluating the workabilities, setting times and compressive strengths of M40 grade concrete mixes made with two different brands of cement and with two different chemical admixtures. The dosage of SNF and

Suitability of commercial superplasticizers for one-part alkali-activated blast-furnace slag mortar
Journal of Sustainable Cement-Based Materials, 2019 Alkali-activated materials are a low-CO2 alternative for Portland cement in construction. However, one major issue in their use is the poor or varying functionality of the currently available commercial superplasticizers.
