FIBERS, COLORS, AND ADMIXTURES The benefits of combining fibers, color, and/or admixtures with concrete is nearly infinite. Most concrete mixes use some type of admixture in their concrete in order to achieve desired properties required for their project. Fibers can increase impact resistance, and in some cases, replace steel reinforcement. Admixtures can accelerate and delay setting time, minimize shrinkage or permeability, make waterproof, increase workability at a given water content, or enhance strength, pumpability, and finishability. Boston Sand & Gravel has provided customers with an array of admixtures since the 1960s. We are happy to assist you with choosing the best concrete product, admixture, fiber, and/or color for your project.
