Abstract
Purpose: The purpose of this work is to study the effect from the chemical additive and ultrasonic treatment of mixing water on strength and other performance characteristics of hydrated cement. Cements CEM I 52.5N and CEM II/A 42.5B are used and factory-made individual clinker minerals (C3S, C2S, C3A, C4AF) manufactured in the Russian Federation.
Methodology/approach: Compression strength testing is conducted on cubic samples with a size of (10×10×10)10–3 m. The particle size distribution is analyzed by a Horiba LA 950 laser analyzer. XRD patterns of curing products and starting materials are obtained by a Shimadzu XRD-7000 X-ray Diffractometer. Ultrasonic treatment of mixing water is conducted on a 0.15/22 OS UZTA system. The chemical additive is nanodispersed silicon oxide and microdispersed calcium carbonate taken in the ratio of 1:2, which is added to the cement paste in the amount of 10 wt. %.
Research findings: It is confirmed that the cement hydraulic activity grows with its increasing grade. It is found that ultrasonic treatment of mixing water activates water with respect to cement. The most significant effect is achieved with the joint modification of cement and water: the strength of hydrated cement increases by 15–30 %.
Value: The obtained data open up prospects for optimizing the cement composition and improving operational properties of building materials.
