About NovoCrete® Technology

Introduction

NovoCrete is an additive used with cement for stablization of various pavement layers mainly insitu work. This help doing in situ stablization layer formation for CTSG/CTSB/CTB/FDR.

Novocrete helps to Prevent premature cracking and creates needle like structure in micro voids which improves compressive strength and flexural strenghth. This enhance C-S-H Gel formation with cement-soil/granular water reaction and improves hydration Properties.

Product description

NovoCrete® is a whitish powder consisting of alkaline and alkaline earth elements or complex compounds. It promotes cement hydration process and inhibits the action of fulvic acids and carbonic acids. Apart from improving the above mentioned parameters, NovoCrete® also promotes the immobilization of pollutants, such as heavy metals and organic parameters, which get permanently embedded in the new crystal structures in the soil. During the chemical reaction ( CaCL2 x 6H20 ) arise Antarcticit (kind of Calcium- chloride Dihydrate) which grows in a trigometrical crystal system. This new aggregate can form needle- crystals up to 15 cm. This growth in combination with the other Novocrete® minerals gives the desired elasticity and strenght to the base layer. Stabilized bases courses treated with cement only, usually combine high stiffness with a high risk on premature cracking. This undesirable combination was regarded as a major handicap for stabilization.

Advantages at a glance

• Much faster construction process
• Roads can be re-opened for traffic already after 24 hours
• Possibility to build roads with and without pavement
• No need for soil exchange or additional gravel material, in-situ material can be used
• 90 day hydration process: next to no cracking with binder from up to 14%
• During the hydration process, long crystal needles are formed, allowing very high bearing strengths With a binder content of >10%, after 1 to 2 days values of at least 150 MN/m2 can be attained, and can continue to increase for up to 90 days
• The stabilized layers show low bending tensile strength. Concrete anchors may be installed
• Water does not penetrate, nor any other fluid, into the stabilized layers, guaranteeing safety from frost
• Longer lifespan as it is water-resistant, and increased acid and salt resistant
• Lifespan can be prolonged by laying a thin wearing course
• No problems with loamy or clayey soils containing high levels of sulphur associated with high cement content
• Adaptable to nearly all soil types - even grainy sands or organic material can be reinforced
• Soils with high levels of salt can be stabilized
• Stabilizing contaminated soils is possible
• No problems from frost, thaw or changes in conditions, as water-resistant base courses may even be constructed from in-situ soils
• Stabilization measures can be customised and adapted to particular soil conditions
• Less to no expenses for maintenance are required for years
• Restoration of surfaces to original condition is possible

Distribution of Tension and Deformations

The Bulk of Distribution of Deformation is wider, reason why, the deformations transmitted are distributed in a greater area, with what the magnitude of the efforts reduces of considerable way, minimizing the deformations in the inferior layers with floors of minor specification and as a con- sequence, drastically increases its useful life.

In the case of Flexible Pavements, the difference is more noticeable. Note that the Deformation Distribution Bulb with „in-situ“ materials + NovoCrete + Portland Cement is wider and shallower, distributing and dissipating the major Efforts in the modified soil layer and the structure with materials conventional distributes greater efforts with less area in materials of lower specifica- tion at greater depth, increasing deformations and decreasing its useful life.
