As a matter of fact, natural pozzolan is denoted as a siliceous or siliceous and aluminous materials, that in itself owns a lot of small or no cementitious values but will, in correctly splited and in the presence of moisture, chemical reactions with calcium hydroxide in a recognized temperature to shape compounds possessing properties well.In fact, these affairs are related to types of natural pozzolans which are so practical in different fields.
what is natural pozzolan?
In this part, we want to speak more about the usages of natural poozolan. In fact, some usages of natural pozzolans are, in decreasing of CO2 emissions associated with Portland cement production. Almost 50 percent Portland cement replacement by a natural pozzolan could mean a decreaseing of such greenhouse gas emissions in cement production by one half, that would have some positive consequences for our environment. On the otherhand, depends on the grindability (in necessary times) and closeness to the construction site, natural pozzolans may particularly lower the available cost of concrete production, dam construction or production of mass housing units as well. As found with ancient concrete , natural pozzolans utilized in normal and natural proportions van basically boost concrete performance and even durability. In addition, the benefits and advantages of most pozzolans which is used far outweigh their disadvantages, it is imperative which is a thorough study of any particular reliable geological source of natural pozzolan is conducted to comprehend its performance essence. This matter also can help to define discretionary usage of materials, in which applicable. In fact, earlier extensive studies found the volcanic ash features to be satisfactory for utilizing in making lime pozzolan cements correctly. the pozzolan materials were blended with ordinary Portland cement in proportions ranging from 15 to 30 percent and performance related parameters were measured precisely.

First of all you should know about different types of artificial pozzolans or even its natural. In fact, It is made by artificial pozzolanic materials. Besides, it is produced by the lowering of high qualified quartz with coal in an electric arc furnance in the manufactures or firms of silicon or ferro silicon alloy as well. Meanwhile, in this process silica fume rises as oxidised water vapour. It will cool, condense and can collected in cloth bags or socks. Besides, the silica fume so collected is further processed to remove and take out impurities and to control particle sizes. On the other hand, the condensed silica fume is crucial silicon dioxide (as chemical icon in form of SiO2) more than 90 percent in non-crystalline form. Moreover, in fact, its shape is spherical and specially fine in size less than 1 micron.
