COÉSIO® is a concrete with compensated shrinkage, formulated with the addition of selected expanding agents to reduce the occurrence of cracking phenomena due to the natural tendency of concrete to shrink in volume. This phenomenon appears in two forms at two distinct times: as plastic shrinkage during the initial setting phase of the concrete and as hydraulic shrinkage during the first week of hardening. In both these phases COÉSIO® reduces the effects of shrinkage thanks to its ability to increase its volume and expand its mass. In addition to this expansive action inherent to concrete, the counteracting forces generated by the formwork help to increase the state of prestress necessary to compensate for subsequent natural hydraulic shrinkage.
Applications
COÉSIO® is suitable for the construction of any type of vertical or horizontal structure where the main requirement is a high degree of effectiveness in limiting the shrinkage effects of the casting during the critical setting phases. To maximise the anti-shrinkage properties of concrete, a good casting method and careful curing are required.Examples:- foundations for large machinery that produce
vibrations
- foundations
- grouting reinforcement of pillars, piers and beams
- restoration of structural elements
- flooring in general
Advantages
- absence of cracks and micro-cracks after proper laying and curing
- high compactness
- high workability
- rapid laying
