Mortar topping, epoxy

Figure 4. Epoxymortar topping The epoxy mortar topping is prepared in kits.

In the ease where the turbine and supports have a minimal eross seetion, then the ability to inerease the stiffness of these pedestals is minimized. Consequently, the objeetive is to eoneentrate on inereasing the mass of the pedestals. This inerease is aeeomplished by filling the eavities with a speeial mortar prepared with epoxy and steel shot. The density of this speeial mortar ean be in exeess of 300 pounds per eubie foot. To injeet this speeial mortar, a pipe has been installed in the aeeess hole that was drilled in the side of the pedestal near the top. These same teehniques ean be employed to stabilize the foundations under mueh smaller equipment.

Of course, floors in a structure receive the greatest abuse, where deterioration occurs in such areas, epoxy resin systems have been widely used for repairs. Industrial floors are now constructed with initial specifications calling for an epoxy mortar, usually, 1/4 inch in thickness, to provide a diemically and physically resistant surface. Slip-resistant aggregates may be embedded in such epoxy toppings. The same tech-... 

Uses Epoxy for water dilution in combination with amine curing agents, forming fine particle size emulsions useful as modifiers for Portland cement, concrete, mortars, stuccos, grouts, as binders for trowel-applied floor toppings, as bond coats, base coats, membrane coatings, and sealers... 

A spalled concrete surface is the beginning of continued disintegration of the concrete. If the cost of replacement is at all comparable with the cost of repair, replacement is recommended. Replacement is also recommended when changing the level of the final surface is impractical. Otherwise, the concrete can be resurfaced with new concrete, epoxy topping, latex mortar, or iron topping.
