Longer term soil-lime pozzolanic reactions lead to the formation of compounds by which the modified material becomes cemented, thus increasing strength and durability (stabilisation). The advantages in drying, workability and performance of the lime amended soil lends the process to numerous applications including: improvement of bulk fill and sub-grade or capping layers temporary (or permanent) Haul Road Construction Drying out and controlling the moisture condition and compactability of wet or plastic soils construction of embankments treatment of sludge Cement Stabilisation Once a clay soil has been made viable by the addition of lime or, if a soil is of a gravel/sand/crushed concrete nature, the addition of cement can greatly enhance the material’s performance. Apart from the obvious strength gain associated with cement addition, other advantages include: increased durability, stiffness and bearing capacity increased resistance to frost and weathering increased impermeability containment of contaminants (subject to testing) greater control of swelling Typical uses for cement stabilised solutions include: sub-base replacement layers in lieu of imported MOT Type 1 high strength capping layers piling mat construction roadbase replacement layers upon which tarmacadam base and wearing course can be applied solidification as a means of treating contaminated soils (i.e. chemically binding free liquid, encapsulating waste particles, chemically fixing hazardous elements) The Company Information Profile Quality Statement Board Profiles Social Responsibility Health & Safety Innovation Careers Projects Case Studies Current Projects Experience SMARTR Basement Construction Residential Construction Soil Remediation Demolition Other Information Contact Us Terms & Conditions Privacy Policy News Contact Us Send © 2016 O'Keefe Website design and hosting by Cyber with Juniper Website Management System
