To maintain quality control on Portland cement, a set of ASTM specifications for both the chemical and physical requirements have been established. A series of "standard" tests have been developed to ensure that these specifications are met.

Portland cement adheres well to lots of materials, especially to other materials made from the same type of ingredients. ASTM Standard C 926, Specification for Application of Portland Cement-Based Plaster, permits direct application of stucco to solid surfaces like concrete and masonry as long as bond is sufficient. Quality Control Program Overview Information on this web page supports the requirements for a Quality Control Program in the production of asphalt, Portland cement concrete (structural), earthwork, cementitious materials, timber, prestressed concrete products, and drainage products. Like recyclate from Portland cement concrete, the quality and characteristics of recyclate from old bricks depends a lot on the strength of the bricks. High-strength (‘engineering’) bricks can produce reasonable aggregates, but softer bricks will generally produce a higher proportion of fines in the mix with less flaky coarse pieces. QUALITY CONTROL AND ACCEPTANCE PROCEDURES FOR PORTLAND CEMENT CONCRETE PAVEMENTS These Special Provisions revise, amend, and where in conflict, supersede applicable sections of the 1999 Standard Specifications for Highway Construction, English and Metric .
