The Romans used Neapolitan yellow tuff zeolites near Pozzuoli.\u00a0<\/span>In Italy it was used in the construction of aqueducts, public buildings and highways.\u00a0<\/span>The combination of lime and zeolite has shown excellent cementitious properties.\u00a0<\/span>For many years, natural zeolite tuffs have been used as cement pozzolans in Serbia, Germany, Italy, Bulgaria, China and Russia.<\/span><\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Due to the properties of zeolite, its high pozzolanic activity, zeolite was used as an active mineral additive in the production of durable, frost-, moisture-, acid-, sulfate-resistant high-strength concretes.\u00a0Such concretes are used in the construction of hydraulic structures, as well as bridges, flyovers, port facilities.<\/span><\/p>

It is known that the introduction of zeolite in an amount of 10-15% allows to reduce the consumption of cement and to use a binder of the optimal ratio in mortars and heavy concrete of class B15-B10.\u00a0When an activated zeolite is introduced into concrete, fractions up to 200 microns in the amount of 10-20% of the mass of cement (M400, M500), plasticizers may not be used, since the zeolite gives high plasticity and workability of the concrete mixture.\u00a0If, nevertheless, a plasticizer is used, then its consumption should be 0.3-0.4% of the dry mass of cement.<\/span><\/p>

The introduction of zeolite into concrete allows increasing the grade of concrete up to 750-800 and the index of water resistance up to W14-20.<\/span><\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Zeolite, which has undergone thermomechanical treatment, can be used in the production of high-strength structural claydite-concrete of grades M300-M700.\u00a0Expanded clay concretes of the above grades with the use of zeolite have a number of advantages over concretes without the use of zeolite – these are their high frost resistance, water resistance, crack resistance.\u00a0In addition, they have a higher resistance to fire conditions than concretes with heavy aggregates.\u00a0This is due to the close values \u200b\u200bof the coefficients of thermal expansion for the aggregate with the use of zeolite and concrete matrix.\u00a0The result is increased operational reliability and durability.<\/span><\/p>

The use of zeolite in solutions makes the solution warm, which allows you to remove the cold bridge when laying.\u00a0The introduction of activated zeolite in the amount of 10% into the solution reduces the thermal conductivity of the solution mixture by 5-10 times.\u00a0The solution becomes elastic, has a high water-holding capacity, does not stratify.<\/span><\/p>

The use of zeolite in concrete and reinforced concrete products reduces the time and temperature of steaming.\u00a0Zeolite is an internal agent for the care of concrete, absorbing and holding water in itself for a certain time, then gradually giving it to the cement, contributing to its complete hydration.<\/span><\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
