Polished Concrete Levels Compare Finishes Concrete

Aggregate exposures range from cream, with very little exposure Class A, to large aggregate exposure up to inch Class D. Because there is very little cut depth, a cream exposure will not remove existing blemishes or surface imperfections in the concrete. A Class D aggregate exposure is very attractive, but requires more aggressive ...

Guide to Polished Concrete Floors

Class A Cream Aggregate Polished surface resulting in little-to-no aggregate exposure. Some light sand exposure. Class B FineSand Aggregate Removes approximately 116 of concrete surface by grinding and polishing. This results in the majority of exposure displaying fine sand aggregate with little-to-no medium aggregate in random locations.

Concrete Exposure Classes

Use Category 1 for concrete exposed to freezing and thawing. Use air content Category 2 for concrete not exposed to freezing and thawing. For class of exposure C-4, the requirement for air entrainment should be waived when a steel trowelled finish is required. The addition of supplement ary cementing

Data Sheet Tolerance for Concrete Surfaces

appearance of formed concrete surfaces, for both in-situ and precast concrete elements. The surface finish quality is specified as one of five classes. Classes 1, 2 and 3 are typical architectural applications where the concrete surface visual quality is important. Tolerances for each class are specified for various aspects of the surface

B. Coarse aggregate for Class A, Class B, or Class C concrete shall be furnished in two sizes Size No. 4 and Size No. 67 as shown hereinafter in Table 03050.1, Coarse Aggregate Gradation Table. The two sizes shall be manufactured, within the specified limits, to produce Size No. 467 when combined in the proper proportions at the batching plant .

Almost any aggregate can be used to produce quality concrete provided the aggregates are durable and clean. Item 421 lists the aggregate requirements. The particle size distribution or gradation of the aggregate is an important characteristic.

Aggregate exposures range from cream, with very little exposure Class A, to large aggregate exposure up to inch Class D. Because there is very little cut depth, a cream exposure will not remove existing blemishes or surface imperfections in the concrete. A Class D aggregate exposure is very attractive, but requires more aggressive ...
