ABSTRACT This report describes models, ABAQUS and Schmidt, to predict the peak temperature in the center of cast-in-place concrete piling. Five concrete piles with varying diameters and made up of concrete mixes with different percentage of fly ash are used. The temperature profiles predicted using the finite element program, ABAQUS, are compared to temperatures predicted by the step-by-step method, ACI 207 Schmidt model. The results show that the ABAQUS model correlates better to experimental results and yields better predictions of the temperature profiles than the Schmidt model. The latter is faster to run but overestimates the peak temperature. Using the results from the ABAQUS model, a specification can be recommended that will result in acceptable concrete for large CIDH piles in the range of 6 to 14 feet in diameter. 17. KEY WORDS 18.

  • Thermal Cracking of Concrete
    CIP 42- Thermal Cracking of Concrete WHAT is Thermal Cracking? Thermal cracking occurs due to excessive temperature dif- ferences within a concrete structure or its surroundings. The temperature difference causes the cooler portion to con- tract more than the warmer portion, which restrains the con- traction. Thermal cracks appear when the restraint results in tensile stresses that exceed the in-place concrete tensile strength. Cracking due to temperature can occur in concrete members that are not considered mass concrete. WHY Does Thermal Cracking Occur? Hydration of cementitious materials generates heat for sev- eral days after placement in all concrete members. This heat Thermal cracks in a thick slab dissipates quickly in thin sections and causes no problems. Courtesy CTLGroup In thicker sections, the internal temperature rises and drops slowly, while the surface cools rapidly to ambient tempera- temperature changes. Another factor is a temperature differ- ture. Surface contraction due to cooling is restrained by the ential between a mass concrete member and adjoining ele- hotter interior concrete that doesn’t contract as rapidly as ments. As the mass member cools from its peak temperature, the surface. This restraint creates tensile stresses that can the contraction is restrained by the element it is attached to, crack the surface concrete as a result of this uncontrolled resulting in cracking. Examples are thick walls or dams re- temperature difference across the cross section. In most strained by the foundation. cases thermal cracking occurs at early ages. In rarer instances Other Structures thermal cracking can occur when concrete surfaces are ex- Temperature cracking can occur in structures that are not posed to extreme temperature rapidly.

    Insight - Civil Engineering(2018.1) Original Research Article Research on Crack Control of Mass Concrete Structure Honglong Su,Dongtang Duan,Zhibin Lu School of Environment and Municipal Engineering, Tianjin Jiaotong University, Tianjin, China ABSTRACT With the development of economy in our country, the scale of construction has become more and more complicated. This cause the problem of mass concrete cracks in industrial and civil buildings increasingly prominent and become a fairly common problem. The problem of mass cracks in mass concrete is very complex and involves all aspects related to the engineering structure. The control of temperature cracks in mass concrete foundation is related to geotechnical, structural, building materials, construction, environment and other multi-disciplinary. The hydrothermal heat released by the mass concrete in the hardening process which produces a large temperature change, and the resulting of temperature stress is the main factor leading to the occurrence of cracks in the concrete, thus aff ecting the integrity of the structure, water resistance and durability, and become structural hidden dangers. Therefore, the mass concrete in the construction must consider the crack control. The reason and control measures of the temperature cracks of mass concrete are analyzed and summarized. According to the specifi c situation, these measures are applied to the concrete large-scale basic engineering construction, and the material selection, mixing ratio, admixture, construction arrangement and pouring process, conservation and other aspects to take a strict control measures. At the same time the basic position of the internal and external temperature diff erence was monitored. The temperature control measures and monitoring results taken for the basic engineering provide a reference for the construction of similar projects and provide the basis for further theoretical research KEYWORDS: mass concrete; crack control; hydration heat; temperature stress 1.

Availability of construction material is less day by day. So we can introduce a new kind of material in construction industry to reduce the cost as well as user friendly material. The main objective of the project, by using the available waste material to introduced in concrete industry. Fully replacement of concrete is not possible, so we can made an attempt to develop partial replacement of concrete material. In the last few decades there has been rapid increase in the waste materials and by-products. Some of the industrial by-products like GGBS, fly ash, copper slag, steel slag, Expanded polystyrene (EPS) have been successfully replaced for cement and concrete in the construction industry. It reduces the consumption of natural resources. Steel slag is one of the materials that is considered as a by-product (waste material) obtained during the matte smelting and refining of copper. It has the physical properties similar to the fine aggregate, so it can be used as a replacement for fine aggregate in concrete. Likewise replacement of coarse aggregate is done by some materials, which makes the concrete light weight.

Both the literal and figurative foundations of these projects will be poured in mass quantities of concrete. Two football field-sized precast segments weighing 11,000 and 9,500 tons were floated 27 miles up the Monongahela River and set down atop the drilled shaft foundation to form the new base of the Braddock lock and dam in Pittsburgh, PA. The mix for the segments contained 60% Holcim GranCem® Slag Cement. Using a higher percentage of slag cement in your mass concrete projects delivers strength, durability and eco-efficiency. Challenges with pouring mass concrete. When pouring mass quantities of concrete, it is a common practice to use varying mixes of portland cement or supplemental cementitious materials such as slag cement or fly ash. These mixes are used to help control the amount of heat generated as the concrete cures and Rock and Roll Hall of Fame – Cleveland, OH helps maintain structural integrity.

  • Optimizing the Use of Fly Ash in Concrete
    CONCRETE Optimizing the Use of Fly Ash in Concrete By: Michael Thomas, Ph.D., P.Eng., Professor of Civil Engineering, University of New Brunswick Introduction Fly ash is used as a supplementary cementitious material (SCM) in the production of portland cement concrete. A supplementary cementitious material, when used in conjunction with portland cement, contributes to the properties of the hardened concrete through hydraulic or pozzolanic activity, or both. As such, SCM's include both pozzolans and hydraulic materials. A pozzolan is defined as a siliceous or siliceous and aluminous material that in itself possesses little or no cementitious value, but that will, in finely divided form and in the Figure 1. Fly ash, a powder resembling cement, has been used in presence of moisture, chemically react with calcium hydroxide at concrete since the 1930s.

These drawbacks become particularly ash, silica fume and a variety of natural pozzolans such as calcined pronounced in cold-weather concreting. Also, the durability of the clay and shale, and volcanic ash.
