Which term is described as available as an aggregate embedded in the surface or an irregular surface texture?

• A. Abrasive
• B. Mortars and adhesive
• C. Cement mortar
• D. Grout

Answer: (A)

The key idea is how a surface gets its texture from hard particles. An abrasive refers to gritty materials that can be embedded in a surface or left as a surface texture to create a rough, irregular feel. These particles act as an aggregate that, when incorporated into a matrix (like cement or a coating), produce the desired textured finish—think of exposed-aggregate or decorative rough surfaces where the grainy particles are seen and felt. Mortars and adhesives are binding agents used to attach materials, but they don’t by themselves create an intentionally rough texture. Cement mortar is also a binding material, and grout fills joints rather than adding surface texture. Because abrasives are specifically about providing that embedded or exposed rough texture, they are the right choice here.
