This process cuts the Portland cement content, a major contributor to greenhouse gas emissions, and uses cement replacement materials. These engineered mixes not only deliver carbon emissions savings, as compared to traditional concrete, but also deliver many higher-performing characteristics. Since 2009, U.S. Concrete and its operating companies have saved more than 1 million tons of CO 2 from entering the atmosphere. To address the Dallas Independent School District's sustainability goals, low-CO 2 mixes were selected for six of the district's schools, and the majority of the materials were locally sourced. U.S. Concrete's local business unit, Redi-Mix, LLC, delivered these sustainable mixes to the following schools: Billy Earl Dade Middle School, Clinton P. Russell Elementary School, Ebby Halliday Elementary School, Thelma Page Richardson Elementary School, W.H. Adamson High School and Wilmer-Hutchins Elementary School. U.S. Concrete's Aridus Rapid Drying Concrete Cuts Construction Schedule and Costs for Billy Earl Dade Middle School The original construction schedule for the Billy Earl Dade Middle School was 14 months, risking failure to meet today's August 26, 2013, opening date. Working closely with the general contractor Satterfield & Pontikes Construction, Inc., and joint venture architects Kell Muñoz and KAI Texas, the construction team selected U.S. Concrete's Aridus Rapid Drying Concrete to shorten the construction schedule. The use of Aridus Rapid Drying Concrete cut the construction schedule by 30 percent (from 14 months to 10 months) and resulted in similar reductions in construction overhead costs.
