چکیده

Common Portland cement was used as the main matrix material and cementations material, fly ash admixture, 30 % wt hydrogen peroxide foaming agent other additives to prepare based condensate porous material. The optimum amount of determined by water absorption release experiment, metal fiber added enhance collecting performance. As increased, rate decreased, content 2.73 %, had better performance, addition could obviously improve collection performance cement-based

Preparation and properties of porous aerated concrete

INTRODUCTION Porous concrete, especially Aerated Autoclaved Concrete (AAC) was first developed by a Swedish engineer between the years 1920 and 1932 [1]. He was searching for a material with the properties of wood, but without the disadvantages of wood. Near the end of World War II, AAC became widely used. Vast areas of cities and industries lay in waste and tremendous rebuilding became necessa...

Preparation of porous apatite granules from calcium phosphate cement.

A versatile method for preparing spherical, micro- and macroporous (micro: 2-10 and macro: 150-550 microm pores), carbonated apatitic calcium phosphate (Ap-CaP) granules (2-4 mm in size) was developed by using NaCl crystals as the porogen. The entire granule production was performed between 21 and 37 degrees C. A CaP cement powder, comprising alpha-Ca3(PO4)2 (61 wt.%), CaHPO4 (26%), CaCO3 (10%)...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Technology of Polymer-cement Mixes Preparation with Specified Rheological Properties Technology of Polymer-cement Mixes Preparation with Specified Rheological Properties

In recent years, many new materials appeared on our construction market: polymer pastes, sealants, primers, foam. In addition, dry mixes have been suffered some changes. Previously, for the bonding of stones, leveling and processing of walls and ceilings lime, clay, alabaster, gypsum, and mixtures were used. Before the use, they are diluted with water. The development of dry mixes conducted in ...

Early-Age Properties of Cement-Based Materials: II. Influence of Water-to-Cement Ratio

The influence of water-to-cement mass ratio (w/c) on early-age properties of cementbased materials is investigated using a variety of experimental techniques. Properties that are critical to the early-age performance of these materials are tested, including heat release, semiadiabatic temperature, setting time, autogenous deformation, and strength development. Measurements of these properties u...
