Admixtures can be natural or manufactured chemicals that are added to the concrete before or during mixing. Admixtures are used in difficult construction situations such as hot or cold weather placements, pumping requirements, or early-age strength requirements. This can enhance workability of fresh concrete and the durability of hardened concrete. There are a few chemical admixtures that are most common: MORE
Using sand helps to reduce the cost. It also limits the amount of shrinking to the concrete as it cures. Concrete sand is a fine aggregate that helps fill the voids between the coarse aggregate and is produced by being crushed at the quarry and then washed through a screen in order to make sure no large pieces of rocks are left. Concrete sand is crucial to use in concrete but the ratio of the coarse aggregate to sand to cement must be just right to produce a strong, resilient concrete mix. MORE
Fly Ash is an environmentally-friendly solution in concrete! It brings down the carbon emissions from Portland cement and is a more durable infrastructure that doesnât need to be rebuilt as often. Fly Ash is a natural product of the coal combustion process. Itâs actually similar to volcanic ash. Many concrete mixes will replace fly ash up to 25 percent but more can be replaced from the concrete. There are many benefits for using fly ash, such as: greater strength, decreased permeability, increased durability, reduced head of hydration (which means less cracking), and reduced efflorescence. Fly ash concrete is also more acid-and fire- resistant. The final color of fly ash in concrete is usually ranging from dark grey to yellowish tan. MORE
Flowable fill is a controlled low-strength material (CLSM) and is self-compacted, cementitious material that is self-leveling, non-corrosive, and has a quick set capability. Flowable fill is used for backfill, structural fill, filling abandoned underground storage tanks, tunnel shafts, and sewers. Controlled strength material is used mostly for safety, the ease of placement and compactions, economics and superior results. MORE
ASTM C 50 Type I/II Cement is a dual designation indicating that the cement will meet either Type I or Type 2 Cement. ASTM stands for the American Society for Testing and Materials. ASTM C 50 is for physical tests, a standard practice for sampling, sample preparation, packaging, and marking of lime and limestone products. Type I is to be used when the special properties specified for any other type are not required. Such applications for Type I are for general construction like most buildings, bridges, pavements, precast units and more. Type II is for general use, more especially when moderate sulfate resistance or moderate heat of hydration is desired. Applications for Type II are for structures that are exposed to soil or water containing sulfate ions. Type II is important because when sulfate attacks concrete is can cause severe damage to concrete structures, when this happens it creates stresses that force the concrete to expand and crack. MORE

Expansion material allows expansion and contraction of a concrete slab to allow movement to occur without causing potentially damaging forces within the slab or surrounding structures. Expansion material is usually needed for concrete driveways, patios, garage slabs, sidewalks, stairways, or light poles. There are many expansion materials available, each with their own pros and cons. MORE
