It is suitable for sealing and/or stabilising sandy soil foundations, and especially for grouting soils for permanent structures such as foundations, tunnels, dams, oil tanks etc. Advantages „ No soil polluting properties - consists entirely of inorganic materials ensuring no pollution of underground water or soil „ Remarkable penetrating abilities - the average particle size of Alofix-MC is 4 microns with a grain size distribution finer than 12 microns. The specific Surface Blaine fineness of 8150 cm² / g, enables penetration comparable to chemical grouts „ High hardened strength - the ultra fine grains of the Alofix-MC are chemically activated, so that curing provides rapid hardening to a high strength. This initial hardening is followed by further hardening during an extended period „ Excellent durability - after hardening by hydration, Alofix-MC acquires impermeability, which protects it from underground and sea water, to ensure extremely long durability „ Easy handling - with its strong dispersive quality, Alofix- MC is highly resistant to separation and sedimentation, which provides protection against damage for the injection equipment, and prevents obstruction of pipework „ Fast set time - the set time of Alofix-MC is generally between 4 - 8 hours Description Alofix-MC, ultra-superfine cementitious soil stabilisation grout is supplied as a ready to use dry powder. MC helper improves the ease of use, viscosity, permeation and strength of the grout. With the addition of MC Helper, a dispersing agent, and clean water, Alofix-MC is a highly permeable grout, suitable for low pressure injection into sandy soil to produce solid foundations. Technical Support Parchem offers a technical support service to specifiers, end-users and contractors, as well as on-site technical assistance.

In the case of Alofix-MC, G85 and G95 are approximately 6 μm and 8 μm respectively. If soil is in a wet condition prior to Alofix-MC injection, compressive strength may be slightly reduced. The required injection pressure depends upon the load pressure at the position to be injected, characteristics of the soil and grouting material, injection rate (speed), expected period of duration of the injection, etc. In general, Alofix-MC is applied at the rate of 2 to 30 kgf / cm². It is also recommended that the injection is carried out at low pressure as much as possible. The required flow rate should be determined on-site after some trial injection, as lowpressure operation with the depressed flow rate results in increased material being required. In sandy soil, the injection rate could be in the order of 10 - 12 litres per minute. March 2014
