Download Improving Concrete and Mortar using Modified Ash and Slag Cements Book in PDF, ePub and Kindle
The use of concrete and mortar containing coal fly ash, blast furnace slag, and other dispersed technogenic materials is one of the major areas of potential resource savings and improving the environmental efficiency and sustainability of construction. Improving Concrete and Mortar using Modified Ash and Slag Cements presents the results of a study of high-tech concrete on composite Portland cement and slag Portland cement. It explains the possibility of significantly improving the properties of cements and concrete with the introduction of superplasticizers and hardening activators. Features: Describes how additives can reduce costs and lead to more environmentally sustainable production Explains the possibility of obtaining high-tech concrete with a high content of ash, slag, and clinker kiln dust Presents the possibility of significant reductions of the most energy-intensive component of cements Examines the calculated dependences for predicting the technical properties of concrete saturated with dispersed technogenic products Explains the methods of calculating the composition of concrete with specified properties of low-clinker cements Suitable for civil and structural engineers as well as for specialists working in the field of concrete technology, students of civil engineering, and researchers of new construction technologies, this book allows readers to understand new and sustainable ways to improve the properties of concrete and mortar by utilizing additives.

Download High Performance Concrete Optimal Composition Design Book in PDF, ePub and Kindle
Concrete and reinforced concrete remain the main building materials for construction of modern fortifications. The book presents experimental and theoretical results allowing production of special high-strength rapid hardening concrete and fiber reinforced concrete. It describes a method for effective proportioning of high-strength fast-setting concrete and fiber reinforced concrete with high dynamic strength as well as selecting proper technological parameters, methodology for design of reinforced concrete structures using such concrete. Particular attention is paid to ensuring the early strengthening of concrete within 24 hours after casting and to constructing structures with limited energy resources at the site.

Download Effectiveness of Ternary Blends in Mitigating ASR Demonstrated on the Modified Mortar-Bar Test Book in PDF, ePub and Kindle
Supplementary cementitious materials (SCMs) are the effective means of improving concrete durability. Combining two SCMs with ordinary Portland cement helps overcome the probable drawbacks of using single SCM. Ternary cementitious systems have become popular in the construction industry, particularly for use in high-performance concrete. In this study, the effectiveness of ternary blends in controlling alkali-silica-reaction (ASR) deterioration was tested in the comparison of a modified mortar-bar method and ASTM C1260-14/C1567-13. Our experiment included the evaluation of 22 binary or ternary combinations of five cementitious materials (Portland cement, metakaolin, low-calcium fly ash, high-calcium fly ash, and slag) tested with two different reactive aggregates. In addition to standard ASTM C1260-14/C1567-13, the mortar mixes were assessed on a modified mortar-bar method of short bars (25 x 25 x 150 mm3) stored at 60°C and >95 % relative humidity. Ternary cementitious blends containing metakaolin and low-lime fly ash proved to be very effective at controlling ASR. In the proposed modified test, a pass/fail criterion of 0.03 % expansion over 60 days was found to be in agreement with the expansion at 14 days of ASTM C1260-14/C1567-13 at 0.10 %.

Download Potential of Portland-Limestone Cement to Improve Performance of Concrete Made With High Slag Cement and Fly Ash Replacement Rates Book in PDF, ePub and Kindle
Aggressive use of supplementary cementitious materials (SCMs) in concrete is becoming more appealing due to potential for cost effectiveness, reduced environmental impact, enhanced durability, and increased sustainability. Constructability, though, is often less attractive as time of set and early strength development can be delayed. This paper investigated the merits of incorporating portland-limestone cement (PLC) to improve concrete sustainability and performance when rounded gravel aggregates (most sustainable for some markets) were used in conjunction with dual SCMs proportioned for 50 % to 70 % total cement replacement. The family of concrete mixtures evaluated have not been widely studied with PLC (in the US or elsewhere). Mixtures containing PLC designed for improved synergies in the US construction market were compared to similar variations containing ordinary portland cement (OPC). PLC was shown to be able to produce concrete mixtures of greater compressive strength and lower set times compared to OPC in some, but not all, conditions. Individual mixture performance varied based on SCM use, PLC properties, and aggregate properties.

Download Cement Industry Book in PDF, ePub and Kindle
Cement is the basis of the building and construction industry and of fundamental importance for many civil engineering applications. As such, the cement industry is one of the key industries worldwide necessary for the current and future sustainable development of society. Despite its undisputed importance, the cement industry is one of those industrial branches predominately responsible for high energy consumption and excessive generation of large amounts of carbon dioxide and other contaminants that significantly endanger human health and the environment and contributes to global warming.In this context, nanomaterials, polymeric materials, and natural additives are being used for cement enhancement in various applications. This book examines these novel materials and their optimization, characterization, and sustainable application in the building industry and for stabilizing hazardous waste.
