This book was released on 1995 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: Test Method for Evaluation of Cement Strength Uniformity from a Single Source (ASTM C 917) in the ASTM Annual Book of Standards, Volume 4.01, Cement, Lime, and Gypsum provides methods to evaluate the cement strength uniformity from a single source. Test data comparing 1976 through 1977 and 1991 show a general increase in strengths over that period of time. In 1976, 45% of the labs had annual average 7-day strengths less than 27.6 MPa (4000 psi), while in 1991 none of the plants had averages below that level. The data show the cement industry, overall, shipped a more consistent product in 1991 compared to 1976 through 1977. The percentage of plants with a standard deviation below 2.1 MPa (300 psi) at 7 days increased from 63 to 81% during that time period. A higher percentage of plants had the total coefficient of variation and corrected deviations below 6%. The testing error remained the same with the 1976 data and the 1991 data, but the testing error coefficient of variation improved.

Available in PDF, EPUB and Kindle. Book excerpt: This article shows how ASTM Method for Evaluation of Cement Strength Uniformity from a Single Source (C 917-82) serves as a valuable tool in ascertaining the uniformity in the quality of cement produced. The results obtained on compressive strength tests of both cement and concrete--the cement being tested at Saudi Kuwaiti Cement Manufacturing Co. (SKC manufacturing quality control laboratory) and the concrete (using SKC cement) at the quality control laboratory of Saudi Arabian Vulcan Limited, a ready mix concrete plant--clearly indicate that there is very good uniformity in quality of cement produced at SKC's factory situated at Khursaniyah (in the Eastern Province of Saudi Arabia) with a capacity of 7000 MT/day of cement clinker due to the level of automation adopted in process control. Thus the article brings out that, in modern cement plants which are usually large in capacity, C917-82 is a suitable yardstick to assess whether the quality control procedures exercised are effective.

Book excerpt: THE SUBJECT OF VARIABILITY OF CONCRETE making materials was first covered in ASTM STP 169C. It was derived from the work of the joint ASTM C01/C09 Task Group on Variability of Concrete-Making Materials. The Task Group provided the impetus for development of guidelines on determining uniformity of concrete-making materials, which eventually became ASTM Standard Practice for Determining Uniformity of Ingredients of Concrete from a Single Source (C 1451).

Download or read book Improving Concrete Quality written by Karthikeyan H Obla and published by CRC Press. This book was released on 2014-06-25 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improve the Quality of Concrete, Improve the Quality of Construction Quality measurement is not prevalent in the concrete industry and quality investment is not seen as potentially generating a positive return. Improving Concrete Quality examines how and why concrete quality should be measured, and includes instruction on developing specifications with the aim of improving concrete quality. Reduce Concrete Variability: Reduce Costs and Increase Volume The first part of the book considers the tangible and intangible benefits of improved quality. The later chapters explore concrete strength variability in detail. It provides a greater grasp of the variation in concrete, as well as a deeper understanding of how material variability affects concrete performance. The author discusses the components of variability (material, manufacturing, testing) and provides steps to measuring and reducing variability to improve the quality of concrete. The text also contains a chapter on data analysis for quality monitoring and test results. Come Away with Practices and Tools That Can Be Applied Immediately: Provides techniques and how specifications can improve concrete quality Offers a clear understanding of the link between the materials (cement, SCM, aggregate, water, air), manufacturing, testing variability, and concrete quality Includes information on analyzing test data to improve quality Improving Concrete Quality quantifies the benefits of improved quality, and introduces novel ways of measuring concrete quality. This text is an ideal resource for quality personnel in the concrete industry. It also benefits architects, engineers, contractors, and researchers.

Available in PDF, EPUB and Kindle. Book excerpt: Summary: This book presents the properties of concrete as needed in concrete construction, including strength and durability. All concrete ingredients (cementing materials, water, aggregates, admixtures, and fibers) are reviewed for their optimal use in designing and proportioning concrete mixtures. Applicable ASTM, AASHTO, and ACI standards are referred to extensively. The use of concrete from design to batching, mixing, transporting, placing, consolidating, finishing, and curing is addressed. Concrete sustainability, along with special concretes, including high-performance concretes, are also reviewed.
