The furan polymers are used as binders in mortars and grouts to achieve chemically resistant brick floors (e.g., carbon brick and red shale brick) and linings. In addition to exhibiting superior chemical resistance, these floors have excellent resistance to elevated temperatures and extreme thermal shock [2,6,7],...

Acid-resisting Cement. The principal types are as follows 1. Silicate an inert filler bonded with silica gel that has been precipitated in situ from Na- or K- silicate in the presence of Na2SiFg, or from silicon ester. 2. Rubber Latex essentially cement sand mixes impregnated with rubber. 3. Synthetic Resin with an inert filler. 4. Sulphur Cements usually with sand as filler. 5. Bituminous Cements. ASTM specifications for these materials are listed in Vol 4-05 of the Annual Book of ASTM Standards, and number some 25, including specifications for mortars and grouts. 

A preacceierated, thixotropic, rapid gel and cure, orthophthalic polyester specifically designed for anchor bolt fixing, mortar and grouting. 

Chemically resistant mortars and grouts are based on organic and inorganic chemistry. They consist of a liquid resin or an inorganic binder fillers such as silica, carbon, or combinations of the same and a hardener or catalyst system that may be incorporated in the filler or added as a separate component. 

The same basic epoxy resin systems are used as monolithic surfacings and epoxy polymer concrete. In addition to these, epoxy phenol novolac is also used to produce mortars and grouts. This is a higher viscosity resin that requires the inclusion of various types of diluents and resin blends. Table 10.3 lists the atmospheric corrosion resistance of the mortars and grouts. 

Furan mortars and grouts are formulated using either 100% carbon or part carbon/silica fillers. Although not normally used as a monolithic surfacing, they are used to produce furan polymer concrete. Either formulation is satisfactory to resist normal atmospheric pollution but more aggressive pollutants might require the use of 100% carbon filler. Furan grouts normally are filled with only 100% carbon filler. 

The same polyester resins are used to formulate mortars and grouts as are used to formulate monolithic surfacings and polymer concretes. Carbon and silica fillers are used in the formulations. Polyester resins have a shelf life limitation and should be stored below 60 F (15°C). Any of the polyester-type resins provide suitable resistance to normal atmospheric corrosion (see Table 10.3). 

Sulfur mortars and grouts are similar to sulfur polymer concrete. Fillers used are either 100% carbon or 100% silica. The sulfur mortars and grouts are... 

MAPEI contributed mortars and grouts for installing the tile floors in five homes that are being renovated after Hurricane Katrina s original devastation and subsequent storms. Mike Daniels and Wilbert Adams, MAPEI employees with extensive tile-setting experience, were on hand to volunteer at the work sites. MAPEI also provided caps for all the volimteers on the project.

To keep compatibility principles in designing grouts for MHS implies the selection of inorganic and relatively low strength potential binders, such as lime-based binding systems, which are the constituents of the most joint mortars of ancient masonries. An exception is the earth block masonries, in which the soil is the main binder for blocks and mortars and grouts should be soil-based mixtures.
