Ready Mix Concrete

Ready-mix concrete refers to concrete that’s manufactured for customers’ construction projects and supplied to the customer on-site as a single product. It is a mixture of raw materials: Coarse Aggregates, Fine Aggregates, Portland Cement, Supplementary Cementitious Materials, water, and chemical admixtures. Concrete mixes are made to meet defined strength, durability, permeability, and surface finish specifications.

  • MAG B 2500 Curb
  • MAG A 3000
  • MAG A 3000 FL
  • MAG A A 4000
  • MAG AA 4000 FL

Concrete strength requirements on projects vary from residential concrete mixes to commercial and structural concrete mixes. Supplementary cementitious materials and chemical admixtures are necessary raw materials in order to reach higher strength levels. Additionally, these added raw materials improve concrete workability, durability, permeability, and finishing characteristics.


ABC Slurry

STS Materials supplies ABC Slurry that meets all local specifications in various strengths and aggregate sizes. A slurry is a mixture of cementitious materials, aggregates, admixtures\additives, and water that forms a soil replacement. CLSM is a self-compacting, flowable, cementitious material primarily used as a backfill, structural fill, or a replacement for compacted fill or unsuitable native material.

Shotcrete is a method of applying concrete, made with smaller-sized aggregates, projected at high velocity through a hose & nozzle system, primarily onto a vertical surface. The impact created by the application consolidates the concrete. Although, the hardened properties of shotcrete are similar to those of conventional cast-in-place concrete. The nature of the placement process results in an excellent bond and requires less formwork. Shotcrete is used in the construction of swimming pools, canal linings, ponds, small lakes, water features, skate parks, retaining walls, tanks, and silos.

Masonry Grout

Masonry grout is a cementitious mixture used to fill cores or cavities in masonry construction. While usually added for structural reasons, grout can also increase fire ratings, security, acoustical performance, termite resistance, blast resistance, thermal storage capacity, and anchorage capabilities. Grout is composed of cement, small-sized aggregate, sand, chemical admixtures, and sufficient water to allow ease of placement and ensure complete filling of the grout space. The high initial water content of typical grout mixes compensates for water absorption by the masonry during and after grout placement. The final water-to-cement ratio is significantly reduced, thus grout develops high compressive strength despite its apparent high initial water-to-cement ratio.
