Slag Cement (GGBFS) - 15 lbs - Strengthens Concrete. Countertops, Art Projects

Description

%100 Pure GGBFS Slag Cement
NEW 15 lb Heat Sealed stand-up pouch with zip-lock closure
This is a perfect quantity to use for Concrete Hardening & Durability Applications or for having on hand in your shop. In a countertop application
with its low permeability and greater resistance to chlorides and sulfates you can expect a more durable and long lasting countertop.
Using slag cement in addition to portland cement in a concrete mixture is a useful method to make concrete better and more consistent. Among the measurable improvements are:
Better concrete workability
Easier finishability
Higher compressive and flexural strengths
Lower permeability
Improved resistance to aggressive chemicals
More consistent plastic and hardened properties
Lighter color
Concrete containing ground granulated slag develops strength over a longer period, leading to reduced permeability and better durability. Since the unit volume of Portland cement is reduced, this concrete is less vulnerable to alkali-silica and sulfate attack. Other uses include GGBS cement, Soil cement, Roller compacted concrete, Road Base, Agriculture/Soil Amendment, and Glass Manufacture.
Dosage:
The normal ratios of aggregates and water to cementitious material in the mix remain unchanged. GGBS is used as a direct replacement for Portland cement, on a one-to-one basis by weight. Replacement levels for GGBS vary from 30% to up to 85%. Typically 40 to 50% is used in most instances.
Appearance
In contrast to the stony grey of concrete made with Portland cement, the near-white color of GGBS cement permits architects to achieve a lighter color for exposed fair-faced concrete finishes, at no extra cost. To achieve a lighter color finish, GGBS is usually specified at between 50% to 70% replacement levels, although levels as high as 85% can be used. GGBS cement also produces a smoother, more defect free surface, due to the fineness of the GGBS particles. Dirt does not adhere to GGBS concrete as easily as concrete made with Portland cement, reducing maintenance costs. GGBS cement prevents the occurrence of
efflorescence
, the staining of concrete surfaces by
calcium carbonate
deposits. Due to its much
lower lime
content and lower permeability, GGBS is effective in preventing efflorescence when used at replacement levels of 50% to 60%.
Strength
Concrete containing GGBS cement has a higher ultimate strength than concrete made with Portland cement. It has a higher proportion of the strength-enhancing calcium silicate hydrates (CSH) than concrete made with Portland cement only, and a reduced content of free lime, which does not contribute to concrete strength. Concrete made with GGBS continues to gain strength over time, and has been shown to double its 28-day strength over periods of 10 to 12 years
Purchasers are aware of basic concrete and cement mixing strategies and are aware of common safety practices when working with cement. Should you be interested we also have access to other admixtures and pozzolans such as Silica Fume, & Fly Ash.
