NovoCrete® О NovoCrete
NovoCrete is a powder-like substance; it contains minerals, in particular. It is used as an adding to ordinary portland cement. Along with the influence on cement and ensuring of optimum water content the formation of crystal structures is getting better in the process of cement hydration. Thus improved firmness, neutralized ph-parameters are reached and waterproof layers are created. Speaker Notes: 3 3

СРАВНЕНИЕ NovoCrete® Ordinary cement srabilization
Cement stabilization with NovoCrete 28 days – hydration process: due to cement shrinkage in case of high content of binding substance a considerable number of fractures appear 90 days – hydration process: almost no fractures with content of binding substance up to 14 % During the process of hydration only short crystal needles are formed, which do not ensure high load carrying capacity. During the process of hydration long crystal needles are formed, ensuring very high load carrying capacity СРАВНЕНИЕ The content of binding substance > 10 % after 1-2 days reaches the parameters per minute МН/m2 and can keep growing during up to 90 days. With the contacnt of the binding substance of up to 3 – 5 % there can be reached parameters of max. 150 МН/m2 Stabilized layers are notable for sufficient firmness upon stretching when bending. Concrete anchors can be used. Stabilized layers are characterized by not sufficient firmness upon stretching when bending. 25

35
NovoCrete® Ordinary cement stabilization Cement stabilization with NovoCrete Stabilized layers are not protected from water penetration (in particular в through the fractures and in coarse-grained soils), this can not ensure frost resistance Water and other liquids do not penetrate into stabilized layer, which ensures frost resistance Very big expenses upon accidents with emission of harmful substances,as the soil is subject to excavation and recycling + costs relating to placing new roadway paving Less cleaning costs upon accidents with emission of harmful substances, as liquid stay on the surface (does not penetrate though the layers) СРАВНЕНИЕ Longer service life due water, salt and acid resistance Short service life due to penetration of water and other liquids into the layers Service life period can be prolonged only by concrete layer or by thick asphalt layer Service life period can be prolonged up to 10 years by thin wear layer. 35

NovoCrete® Ecolocical compatibility NovoCrete is ecologically compatible substance, 100% of which is recycled Contaminated soils can be stabilized and immobilized during one working stroke. Placed layers can be removed from road sections thus it is possible to bring them back to the condition which existed prior to the construction. For that purpose the layers are milled by special cutters and placed once again. 44
45
СРАВНЕНИЕ NovoCrete® Ordinary cement stabilization
Cement stabilization with NovoCrete Without a wear layer sectiones stabilized in an ordibary way may need repair in a year or even erlier due to periodical freezing and defrosting. No problem connected with periodical freezing and defrosting, as it is possible to create a water resistant bearing layers even from soils available at the location. Stabilization actions may be adapted to the conditions and soils at a particular section Adaptation to particular conditions and soils is impossible СРАВНЕНИЕ Expensive repair works can be required whithin a short period of time Repair costs can be substantially lowered. It is not possible to restore the initial state of the section It is possible to restore the initial state of the section 45
