Elite products are designed to give you an edge in specialty applications with new custom products always being considered and developed.
PERFORMANCE FLOW SELF CONSOLIDATING CONCRETE (SCC)
United Materials can deliver to your job site our award winning, self-consolidating concrete. Performance Flow, a highly flowable, non-segregating mix that can easily fill formwork and encapsulate the most congested reinforcement, without any mechanical vibration. Its unique properties give it significant economic, aesthetic and engineering advantages.
Performance Flow is easier to pump, flows into complex shapes, and minimizes voids. With its high strength, superb finish and improved productivity, Performance Flow is fast becoming the product of choice with Architects, Engineers, and Contractors.
Performance Flow mixes are also available for horizontal applications for overlays or flooring applications.
CLIMATE CONTROL MIX
United Materials is pleased to announce our latest innovation in concrete for foundations. ClimateControl Mix is designed to allow contractors to place foundations in freezing weather with a minimum amount of protection.
ClimateControl Mix is designed in three separate categories: CCM20, CCM25, and CCM30. Ambient temperature at the time of placement dictates which mix should be used.
• ClimateControl Mix is delivered to the site at a 5″ slump. If a higher slump is desired. United Materials’ Quality Control will determine the amount of plasticizer that is needed to obtain the proper slump.
• ClimateControl Mix is designed to set within five hours after the concrete is originally batched.
• ClimateControl Mix requires minimal protection (plastic or straw covering the top to protect the top surface of the wall from freezing). When temperatures are projected to be below 20°F it is recommended that blankets be placed over the wall for a minimum of 24 hours.
PERFORMANCE FIBER REINFORCED CONCRETE
Performance Fiber Reinforcement is the best way to ensure correct location of reinforcement in your concrete slabs and elevated decks. Performance Fiber Reinforcement helps your concrete resist early-age cracking, and contributes to long-term durability. A variety of Performance Fiber Reinforcement Systems are available to replace wire mesh and light rebar in slabs and elevated decks.
Performance Fiber Replacement Systems easily replace common 10 gauge thru 4 gauge wire mesh, and light rebar mats such as #3 and #4 bar.
Pervious concrete is a special type of concrete with a high porosity that allows water from precipitation and other sources to pass directly through, thereby reducing the runoff from a site and allowing groundwater recharge. The high porosity is attained by a highly interconnected void content. Typically pervious concrete has little or no fine aggregate and has just enough cementitious paste to coat the coarse aggregate particles while preserving the interconnectivity of the voids. Pervious concrete is traditionally used in parking areas, areas with light traffic, residential streets, alleyways and pedestrian walkways.
As regulations further limit storm water runoff, it is becoming more expensive for property owners to develop real estate, due to the size and expense of the necessary drainage systems. Pervious concrete reduces the runoff from paved areas, which reduces the need for separate storm water retention ponds and allows the use of smaller capacity storm sewers. This allows property owners to develop a larger area of available property at a lower cost.
An experienced installer is vital to the success of pervious concrete pavements. As with any concrete pavement, proper subgrade preparation is important.
EPA recommends that pervious concrete pavement be cleaned regularly to prevent reduction in permeability. Cleaning can be accomplished through vacuum sweeping or pressure washing.
