Nanoscience and Nano Engineering in Concrete Advances , A Review
This paper reviews some progressive studies and innovations in cement and concrete materials in nano field. Due to the widespread acceptance of the special properties of nano materials and using them for engineering concrete performance, understanding and directing their properties are not achievable without instructing concepts and investigating interactions among components. Due to ach...
متن کاملPressure Stimulated Current emissions on cement paste samples under repetitive stepwise compressional loadings
The electric signals detection technique that is described here has been applied on several geomaterials in the past and on cement based materials lately. In this work cement paste samples were studied regarding electric signal emissions during axial stress application processes and specifically when subjected to repetitive loadings and unloadings in the in the range where crack opening and pro...
متن کاملEarly-Age Properties of Cement-Based Materials: I. Influence of Cement Fineness
The influence of cement fineness on early-age properties of cement-based materials is investigated using a variety of experimental techniques. Properties that are critical to the earlyage performance of these materials are tested, including heat release, temperature rise, chemical shrinkage and autogenous deformation. Measurements of these properties for two cements of widely different fineness...

In the drive to produce more sustainable concretes, considerable emphasis has been placed on replacing cement in concrete mixtures with more sustainable materials, both from a raw materials cost and a CO2 footprint per...
متن کاملApplication of grey GIS filtration to identify the potential area for cement plants in South Khorasan Province, Eastern Iran
Cement-based materials are fundamental resources used to in construction. The increase in requests for and consumption of cement products, especially in Iran, indicates that more cement plants should be equipped. This study developed a geographical information system using pairwise comparison based on grey numbers to identify potential sites in which to set up cement plants. A group of five exp...
