Quality Materials

At Bradley Concrete and Lambcon Ready Mix, we strive to provide our customers with the finest quality concrete available on the market. In order to do so, we have carefully selected the most experienced team of suppliers available in our area. The following is a list of the materials most commonly combined to make a yard of our “premium mud”:

Portland Cement: Type I, Conforming to ASTM C150 (AASHTO M85) produced by Buzzi Unicem USA. Click this link for a brief history and composition of Portland Cement.

Fly Ash (Supplementary Cementitious Material): Class F Fly Ash with pozzolanic properties, Conforming to ASTM C618 (AASHTO M295) produced by SEFA Group. To explore the advantages of Fly Ash, please visit SEFA.

Coarse Aggregate: Clean, hard, strong, durable crushed dolomitic limestone free of absorbed chemicals, coatings of clay, and other fine materials. Coarse aggregates are any particles greater than 0.19 inch (4.75 mm), but generally range between 3/8 and 1.5 inches (9.5 mm to 37.5 mm) in diameter. The coarse aggregate at all locations Conforms to ASTM C33 (AASHTO M80).

Fine Aggregate: Fine aggregates generally consist of natural sand or crushed stone with most particles passing through a 3/8-inch (9.5-mm) sieve. We carry two types of fine aggregate:

MateralsMaufactured Sand: Clean, hard, strong, durable crushed dolomitic limestone free of absorbed chemicals, coatings of clay, and other fine materials. Manufactured sand is jagged at the particulate level and is preferred in applications where enhanced durability is necessary. Our manufactured sands Conform to ASTM C33 (AASHTO M6/M43).

SandNatural Sand: Clean, hard, strong, durable silica sand free of absorbed chemicals, coatings of clay, and other fine materials. Natural sand is more rounded at the particulate level and is preferred in applications where enhanced wearability is necessary. Our natural sands conform to ASTM C33 (AASHTO M6/M43).

Chemical Admixtures: The Admixture Systems business of BASF Construction Chemicals is a leading provider of innovative admixtures for specialty concrete used in the ready mix, precast, manufactured concrete products, underground construction and paving markets throughout the North American region.

Air Entrainment: MB-AE 90 air-entraining admixture is for use in concrete mixtures. It meets the requirements of ASTM C 260, AASHTO M 154 and CRD-C 13.

Mid Range Water Reducer: PolyHeed N multi-component, chloride-bearing, mid-range water-reducing admixture meets ASTM C 494 requirements for Type A, water-reducing admixtures.

High Range Water Reducer: Rheobuild 1000 high-range, water-reducing admixture is formulated to produce rheoplastic concrete. Rheoplastic concrete flows easily, maintaining high plasticity for time periods longer than conventional superplasticized concrete. Rheoplastic concrete has the low water-cementitious materials ratio of no-slump concrete, providing excellent engineering (hardened) properties. The slump-retention characteristics of rheoplastic concrete permit the addition of Rheobuild 1000 admixture at the batch plant. Rheobuild 1000 admixture meets ASTM C 494 requirements for Type A, water-reducing, and Type F, high-range water-reducing, admixtures.

Retarding Admixture: Pozzolith 300 R ready-to-use, liquid admixture is used for making more uniform and predictable high-performance concrete while retarding its setting time to facilitate placing and finishing operations. It meets ASTM C 494 requirements for Type B, retarding, and Type D, water-reducing and retarding, admixtures.

Accelerating Admixture: Pozzolith 122 HE ready-to-use, liquid admixture is designed to make more uniform and predictable quality concrete while accelerating setting time and strength development. Pozzolith 122 HE admixture meets ASTM C 494 requirements for Type C, accelerating, and Type E, water-reducing and accelerating, admixtures.
