  • Reducing Cement Content in Concrete Mixtures
    No. 0092-08-08 Wisconsin Highway Research Program • http://wisdotresearch.wi.gov/whrp December 2011 Reducing Cement Content in Concrete Mixtures oncrete mixtures contain crushed rock or gravel, and sand, bound together by Portland cement in combination with supplemental cementitious materials (SCMs), which harden through Ca chemical reaction with water. Portland cement is the most costly component of concrete mixtures, and its production creates significant amounts of green house gases. To reduce costs and environmental impacts, current WisDOT practice allows a for replacement of a portion of Portland cement supplemental cementitious materials (SCMs) such as coal fly ash or slag cement, both industrial by-products of coal and iron production, respectively. WisDOT has set a maximum limit on Portland cement replacement through use of SCMs to ensure its performance on concrete pavements. Therefore, the only opportunity to reduce the usage of Portland cement is to lower the required cementitious materials content for WisDOT approved mix designs. The potential benefits in terms of economic costs and environmental impacts are significant, however decreasing the cementitious materials content of a mixture too drastically can reduce pavement strength and durability. It can also reduce workability, or the ease with which a mixture can be compacted and placed during construction. What’s the Problem? Research was needed to help determine the minimum amount of cementitious material that WisDOT can use in its concrete mixtures and still preserve pavement performance. Several other upper Mid- western states allow the use of concrete mixtures with a lower minimum cementitious material content PUTTING RESEARCH TO WORK TO RESEARCH PUTTING than currently required by WisDOT specifications, but there is a lack of data on the long-term perfor- mance of pavements built with these mixtures.

C24 (characteristic value of concrete, 24 MPa) was used in the experiment conducted. Ordinary Portland cement (OPC), high fineness and SO3 OPC (HFS_OPC), and Early Portland cement (EPC) were selected as the study materials. The unit weights of cement were set to OPC 330, 350, and 380. Further, a concrete mixture was prepared with a triethanolamine (TEA)-based chemical admixture to HFS. A raw material analysis was conducted, and the compressive strength, temperature history, and maturity (D h) were examined. Then, the vertical formwork removal time was evaluated · according to the criterion of each country.

  • MATERIALS August 2009
    MATERIALS August 2009 1006 PORTLAND CEMENT CONCRETE 1006-1 General Requirements This specification deals with Portland cement concrete. Included are component materials, design, mixing, transporting, and curing, as covered in the Standard Specifications. Placing and finishing concrete are covered by Specifications 401 and 601. Utility concrete is covered by Specification 922. Refer to the Standard Specifications and Materials Group Policy & Procedures Directives Manual for additional information on Portland cement concrete inspection guidelines. Good consistency control of concrete is of primary importance. It should be noted that other factors being equal, an increase in the water cement ratio of 0.4 gallon (1.5 liters) per sack of cement will result in an increase in slump of approximately 1 inch (2.5 millimeters) thereby causing a potential loss in compressive strength of about 100 pounds per square inch (700 kilopascals). Over-watered concrete also increases segregation and shrinkage. This is not to say that concrete having a very low slump should always be used. Good judgment must be exercised. The concrete Inspector should be aware of the factors which affect the slump of a concrete mix. The following are some of those factors: 1. Variations in water content have a very pronounced effect on the slump. A change of 1% in the amount of free moisture in the fine, or 3% in the coarse aggregate can change the slump about 1/2 inch (12 millimeters). 2. A change of 1% in the amount of entrained air may alter the slump by approximately 1/2 inch (12 millimeters). An increase in air causes an increase in slump.

Tech.6 th Semester Civil Department JNGEC Sundernagar, Mandi (H.P) – 175018 ABSTRACT 20 th century is known as the concrete century as during this century cement-industries has contributed a lot towards the development of the society .So moving toward the 21 st century has bought new revolution in this field .One of them is Eco-concrete .Eco-concrete is a new type of concrete which is being developed to solve the waste management problem of the municipal and the industries. It will also help the environment by recycling the waste produced by big industries which otherwise would have been dumped in landfills or seas etc. The eco-concrete is not a completely different concept but is same as that of ordinary concrete but the difference is that it uses supplementary cementing materials. These supplementary cementing materials are a class of materials that can be used in the manufacturing of concrete as partial replacement of Portland cement. The most frequently used SCMs are: fly ash – a by-product of coal-fired power plants; silica fume – also known as micro-silica. Less-commonly-used SCMs include: natural pozzolans (or volcanic ash) .There are numerous opportunities like making environmental friendly constructions, restoration of environment by removal of CO 2, conservation of energy as this requires less heat during its construction etc on the other hand there are some problems or we can say challenges that we need to face for instance the conservative behavior of the construction companies. But sooner or later we have to go for this so why not now? Keywords:-Eco-concrete, Supplementary cementing materials, Advantages of Eco-concrete 1.

  • Alkali-Silica Reaction (ASR) Brief
    Materials Bulletin: Alkali-Silica Reaction (ASR) Brief Why is ASR Bad? ASR can cause serious expansion and cracking in concrete. This can result in major structural problems, which can lead to costly removal and replacement. The reaction can occur years after the concrete was placed. Structures most at risk are bridges, hydraulic structures, exposed frames, pavements, and foundations. What is ASR? ASR is a reaction between the alkali hydroxides in concrete and reactive forms of silica in the aggregate. The reaction forms a gel that swells when moisture is present. The two step process can be visualized as: 1. Alkali + Silica → Gel reaction Product 2. Gel reaction Product + Moisture → Expansion Factors Affecting ASR For the reaction to occur the following three conditions must be present: 1. Sufficiently high alkali content of the cement 2. Reactive forms of silica in aggregate 3. Sufficient Moisture If one of these three conditions is missing the reaction cannot occur. How does NC DOT Mitigate the Problem? The best way to avoid ASR is to take appropriate precautions before the concrete is placed. Section 1024-1 of the NC DOT Standard Specifications for Roads and Structures addresses these precautions. 1. The alkalinity of any cement, expressed as sodium-oxide equivalent, shall not exceed 1.0%. 2. For mix designs that contain non-reactive aggregates and cement with an alkali content less than 0.6%, straight cement or a combination of cement and fly ash, cement and ground granulated blast furnace slag or cement and microsilica may be used. The pozzolan quantity shall not exceed the amount shown below.
