Investigation of nano structured mesoporous silica effect on compressive strength properties of normal concrete

In this last decade the researchers invest in nanotechnology in order to make a new generation of concrete materials for getting stable concrete structures. The operation of basic cement materials is intensely depends on solid particles’ traits in nanosize dimension like particles of silicate, calcium, hydrate, or nanometer porosities in the interior transitive space between cement and stone particles. In this laboratory research, these four experiments include a mixture of two series consist of nanosilica and two series of normal concrete that are totally used sixteen cubic samples. The effect of nanosilica with mesoporous MCM-41 is surveyed on normal concrete’ compressive strength. Mesoporous silica’ nanoparticles have the measurement of surface more than 600 . Based on the definition of IUPAC, the mesoporous’s particles have the size of cavities in the range of 2 to 50 nanometer. The production of these compositions are possible by templating method in a chemical process. To study the microstructure of mesoporous silica particles are used the electron microscope’s pictures SEM and TEM. The results of research are representative of increasing compressive strength in a definite rate that decreases because of using a specific level of nanomaterials
