WHAT IS AN INTEGRAL COLOUR ADMIXTURE?
Integral colour admixture is a powder or liquid added to the concrete at the ready-mix plant or in the mixing truck. The concrete is colored throughout the concrete slab. Generally used with a gray portland cement mix design, the products result in subtly muted earth tones. The integrally colored concrete can be placed full-depth or as 50 mm topping over the structural slab.
SIKA INTEGRAL COLOURS are added to the concrete mix at the batch plant or at the jobsite. When the concrete is poured, it is consistently coloured all the way through the mix. Integral colour is typically the most cost effective way to add colour to concrete, and it can be used alone or in conjunction with other concrete colouring and finishing techniques to create a variety of appearances.
Sika’s Integral Colors are a precise blend of non-fading, synthetic iron oxides which produce uniform, permanent, streak-free colours in all types of architectural concrete. This includes cast-in-place, precast, and dry-cast concrete floor slabs, walls, steps, sidewalks, curbs, columns, arches, blocks, pavers, and other decorative objects.
What are the advantages of using Integral Color?
A key component of Sika Integral color is our colour-matched concrete curing compound. Used during concrete placement, it reduces surface cracks and colour variations that can be caused by uneven drying and efflorescence that commonly occurs in warm, windy, or dry environments. In addition, all Sika Integral Color conforms to ASTM Standard C 979 (Standard Specification for Pigments for Integrally Colored Concrete). Sika Integral Colors can also be used to help mitigate the Urban Heat Island Effect through the use of special reflective pigments.
