Aggregate, Volume 5, Issue 1, February 2024.A spontaneous yet controllable strategy is developed to realize the construction of a series of sophisticated hierarchical microstructures on mineral surface in fluids through the coupled dissolution–precipitation chemistry. This work offers new design principle of facilely fabricating various bespoke microstructural surfaces, hierarchical ...

Calcium aluminate cements (CACs) are used in applications requiring rapid strength development, refractory performance, and chemical resistance. However, their early hydration can be too slow for rapid overnight construction, where an opening flexural strength of 2.8 MPa (400 psi) is required within four hours.

Effect of B2O3 on Volume Stability and Strength of Corundum-based Castables
High Temperature Materials and Processes, 2017 Calcium aluminate cements (CAC) with 0.21 wt% B2O3 and without B2O3 were used as binders of corundum-based castables. The properties of the castables with and without B2O3 after heat treatment at 110 °C, 1,100 °C and 1,450 °C were investigated, with ...

Steel Corrosion Behavior of Reinforced Calcium Aluminate Cement-Mineral Additions Modified Mortar
, 2021 Mineral additions can eliminate the conversion in calcium aluminate hydrates and thus inhibit the future strength retraction of calcium aluminate cement (CAC). However, the impacts of these additions on the protection capacity of CAC concrete in relation

Calcium aluminate cement concrete: durablllty and conversión. A fresh look at an old subject
Materiales de Construccion, 1992 This paper re-examines the relationship between durability and conversion of calcium aluminate cement concretes, CACC. Conversion is a natural and inevitable process whereby these materials reach a stable mature condition.
