Glazed-over chips on the edge or corner of the body of a tile.
Any fractures in the body of a tile visible both on face and back.
See Fire, bisque.
The fineness of powdered materials such as cement and pozzolans, expressed as surface area usually in square centimeters per gram, determined by the Blaine apparatus.
A small blister or bubble.
The autogenous flow of mixing water within, or its emergence from newly placed concrete or mortar; caused by the settlement of the solid materials within the mass; also called water gain.
To mix or make homogeneous.
The development during firing of enclosed or broken macroscopic vesicles or bubbles in a body, or in a glaze or other coating. (ASTM C 242).
A square of tile specially made for changing direction of the trim.
A visible exudation or efflorescence on the surface.
Green marks or stains on the face of a tile. Blunging. The wet process of blending, or suspending ceramic material in liquid by agitation. (ASTM C 242).
The structural portion of a ceramic article. This term also refers to the material or mixture from which the article is made. (ASTM C 242).
The adherence of one material to another. Effective bonds must be achieved between the mortar and scratch coat, between the tile and mortar, and between the adhesive and backing.
A substance applied to a suitable substrate to create a bond between it and a succeeding layer as between a subsurface and a terrazzo topping or a succeeding plaster application.
Calcined bone consisting essentially of calcium phosphate. (ASTM C 242).
A translucent china made from a ceramic whiteware body composition containing a minimum of 25 percent bone ash. (ASTM C 242).
A material used to prevent adhesion of newly placed concrete and the substrate.
A material used between the back of the tile and the prepared surface. Suitable bond coats include pure portland cement, Dry-Set portland cement mortar, latex-type portland cement mortar, organic adhesive, and the like.
The brick trowel is larger than the buttering trowel. The most popular size used by tilesetters is 5″ wide and 11″ long. It is used when any preparatory brick work has to be done. Some tilesetters use it for quarry and terra cotta tilework. Its greater surface and weight are advantageous in the buttering and tapping in of the larger tiles.
A straightedge used as a starting line for the laying of tile. The straightedge can be blocked up to support tile over an opening.
The slab or other structure forming the travel surface of a bridge.
Colorless or colored ceramic glaze having high gloss. (ASTM C 242).
The surface texture obtained by stroking a broom over freshly placed concrete. (See also Brushed surface.)
The second coat in three-coat plaster application.
A sandy texture obtained by brushing the surface of freshly placed or slightly hardened concrete with a stiff brush for architectural effect or, in pavements, to increase skid resistance. (See also Broom finish.)
A tool comprising a large, flat, rectangular piece of wood, aluminum, or magnesium usually 8 in. (20 cm) wide and 42 to 60 in. (100 to 150 cm) long, and a handle 4 to 16 ft. (1 to 5 cm) in length used to smooth unformed surfaces of freshly placed concrete.
A trim tile with a convex radius on one edge. . This tile is used for finishing the top of a wainscot or for turning an outside corner.
A type of bullnose trim with a convex radius on two adjacent edges.
Increase in the bulk volume of a quantity of sand in a moist condition over the volume of the same quantity dry or completely inundated.
Graph of change in volume of a quantity of sand due to change in moisture content.
Ratio of the volume of moist sand to the volume of the sand when dry.
The official charged with administration and enforcement of the applicable building code, or his duly authorized representative. ,
A group of not more than four parallel reinforcing bars in contact with each other, usually tied together.
A coarse fabric of jute, hemp, or less commonly, flax, for use as a water-retaining covering in curing concrete surfaces; also called Hessian.

The spreading of a bond coat (followed by a mortar coat, a thin-setting bed mortar, or an organc adhesive) to the backs of ceramic tile just before the tile is placed.
The blade of the buttering trowel is 4’/s’ wide and 7″ long. It is used in buttering pure cement to tile, a method commonly used in the eastern states. The trowel is more efficient than the pointer for working on the larger and heavier tiles because more weight can be placed on it.
A plain square joint between two members.
Tile that have projections on the bondable side. Many of, these projections are round and therefore the term buttonback. Some projections are quite thick and can also be other shapes, such as square.
