2017-9-3 Fine Sand After collecting the sieved recycled fine aggregate, we use this material for preparing cube for cement mortar test to determine the cementing properties of recycled fine as a substitute of cement in various percentages which is shown in Fig. 5. Then we compare it with fine sand which has no cementing property.

The porous mortar and fine cracks are also responsible for the high water absorption of the RAs. Furthermore, the high silt content on the surface of the RA particles may also help to increase the rate and amount of water absorption. R. Hui, The Evaluation for Property of Recycled Coarse Concrete Aggregate Basing on Distance Method, Beijing
2017-8-30 1. Introduction. The concept of high-performance concrete (HPC) has evolved with time and is nowadays very widespread. In its origin was the term high-strength concrete (HSC) that was not able to completely/precisely translate the characteristics of some mixes, namely when durability requirements were also specified, sometimes prevailing over strength requirements.
Recycled concrete as fine and coarse concrete properties of using recycled fine aggregate with natural coarse aggregate have been reported else .

Performance evaluation of structural concrete using controlled quality coarse and fine recycled concrete aggregate (RCA). Five mixes with water-to-cementing material (w/cm) ratio of 0.40 were produced with various RCA contents and tested against two 0% RCA control mixes made with General Use (GU) cement, and General Use Limestone cement

The high absorption of fine recycled aggregates is indicated as the main difference with respect to fine natural aggregates. This property determines the extra amount of water to be added during mixing to avoid a loss in workability when these aggregates are used for making concrete. Although several methods have been proposed for its determination, none of them has been standardized or has

Brick is one of the most common building materials, and it is also one of the largest components of waste generated from both construction and demolition. Reuse of this waste would reduce the environmental and social impacts of construction. One potential bulk use of such waste is as a cementing agent for soil stabilization. However, this is currently limited by the need to mill the residue to

2017-10-6 The cementing property of the paste results from a chemical reaction between the cement and water, called hydration. It is a reaction that requires time and favourable conditions of temperature and moisture. “Curing” is the provision of favourable temperature and moisture conditions over a period of
The self-cementing effect was evaluated through physical and chemical characterization tests, unconfined compressive strength tests for different curing times, and scanning electron microscopy. The results enabled the evaluation of the behavior of these samples and the effects of the addition of these materials to natural soil.

The introduction of recycled aggregates (RA) in concrete creates changes in their properties and differences in the results of the evaluation tests of ASR. Existing bibliography emphasizes special care in the evaluation of RA and concrete with recycled aggregate (CRA) for ASR and changes are proposed to the existing test methods.

The uses of powder diffraction in the study of Portland cements and new eco-cements (those that release less CO2 in their fabrication processes) are highlighted. Firstly, the uses of powder diffraction for analysing the anhydrous commercial cements (Portland, calcium aluminate and calcium sulfoaluminate) are reviewed. Online Rietveld refinement in Portland cement factories is discussed.
