Available in PDF, EPUB and Kindle. Book excerpt: Water bath methods for accelerating the strength development of portland cement concrete were investigated in a two phase study as follows. Phase I - Participation in a cooperative accelerated strength testing program sponsored by the American Society for Testing and Materials. The three methods studied consisted of; (1) curing immediately after casting in 95°F water for 24 hours, (2) curing in boiling water for 3 1/2 hours, commencing 23 hours after casting, and (3) curing in boiling water for 15 hours commencing after the concrete reached a penetration resistance of 3500 psi (fixed set). Phase II - A study of the effects on the results of the fixed set accelerated curing methods of curing water temperatures from 95°F to 212°F. Also considered were certain heat transfer parameters relevant to strength development. The major conclusions were: Phase I 1. The fixed set boiling method is the most efficient and reliable of those studied. 2. Water bath accelerated curing is more efficient for high than for low strength concretes. 3. Water bath and standard moist curing produce strength results of about equal reproducibility. Phase II 1. Accelerated curing efficiencies are directly proportional to the total relative amounts of heat released by the concretes during accelerated curing. 2. Boiling (212°F) water is not conducive to optimum curing efficiency. 3. Optimum water bath temperatures for accelerated concrete strength development range approximately from 165° to 180°F. The duration of accelerated curing is not critical for the fixed set boiling method.

Available in PDF, EPUB and Kindle. Book excerpt: Forty-eight different concrete mixes were designed to investigate the influence of cement types (II, III, and V), cement contents (450, 550, and 650 lb. per cu. yd.), water cement ratios (0.4, 0.5, and 0.6), admixtures (accelerator, retarder, and air entraining agent), and initial mixture temperatures (50°F, 70°F, and 90°F) on the temperature development of autogenous accelerated cured concrete cylinders. A total of 940 concrete cylinders were made incorporating autogenously cured cylinders, 28 day, 91 day, and 1 year moist cured cylinders, and autogenously cured cylinders instrumented for temperature and moisture measurements. The project involved routine testing for slump, unit weight, air content, time of set, and compressive strengths. Additional measurements of temperature development and moisture movement were made. This report describes the influence of concrete mixture variables and initial mixture temperatures on the temperatures developed during autogenous accelerated curing and the relationships among the temperature parameters resulting from the measurements. The report lists eleven observations and conclusions.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the result of a Special Issue published in Applied Sciences entitled “Low Binder Concrete and Mortars". The main aim of this work is to highlight practical approaches that facilitate the production of low binder content concrete and mortar with an acceptable level of technical performance (e.g., mechanical and durability) and environmental impacts (e.g., ecotoxicological and global warming). Its contents are organized in the following sections: Developing Zero-Cement Binder; Ecotoxicological and Chemical Characteristics of the Non-conventional Materials Used to Replace Cement and Natural Aggregates; Reduce the Environmental Impacts and Resources Use of Binders; Modify the Characteristics of the Cement-Based Materials; Low Binder Concrete On-Site Application; Sustainable Cement-Based Materials in Road Engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Through a literature study, approximately fifty methods of measuring moisture were investigated to ascertain a suitable method for use in measuring moisture changes in 6 inch by 12 inch concrete cylinders cured by the autogenous accelerated curing method. The resistance method was selected and the Bouyoucos moisture gage was evaluated in the laboratory to determine its limitations and capabilities. Operation and calibration procedures were developed and the moisture gages used in the autogenous accelerated curing study were grouped and calibrated in a statistically defensible manner. Correction factors for the influence of salt ions and temperature were also developed. Results of this study led to the following conclusions: 1. Of the various methods described in the literature, the Bouyoucos moisture gage was judged to be a satisfactory method of measuring moisture in the concrete cylinders subjected to autogenous curing. 2. The influence of salt ions and temperature on the moisture gage resistance can be measured and the necessary correction factors applied to the results.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Ready Mixed Concrete Technology contains the proceedings of the first International Conference on Ready-Mixed Concrete held at Dundee University in Scotland from September 29 to October 1, 1975. Contributors focus on the significant progress that has been made in ready mixed concrete technology. Some practices are highlighted along with possible areas for research. This text is organized around seven themes; the first of which deals with plant and equipment. Production methods and their development in the ready mixed concrete industry are reviewed, along with developments in batching plant and equipment to meet the needs of the ready mixed concrete industry. The chapters that follow explore the materials used in making concrete, properties of fresh and hardened concrete, mix design and quality control, and transportation and placing. The final section discusses the economics of ready mixed concrete, with emphasis on the cost of placing concrete by pump and the relative economics of alternative materials in Portland cement concrete. This book will be of interest to ready mixed concrete producers, their customers in the construction industry, and their suppliers of concrete materials, plant, and equipment.
