Concrete slabs with exposed aggregate finishs are becoming increasingly popular for swimming pool decks, patio floors, driveways and sidewalks. The following discussion is a description of a good method that does not require retardants or any special admixtures. The labor involved is little more
The Translucent Color Enhancer is not a solid or opaque stain. It's translucent, meaning you can see through it. This is why the Enhancer is used to restore or revitalize exposed aggregate! These images (below) merely simulate how the translucent Enhancer tints exposed aggregate with a new hue and allows the aggregate to show through the tint.

Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently a lime-based cement binder, such as Portland cement, but sometimes with other hydraulic cements, such as a calcium aluminate cement.
Q. I have a client who wants to place a thin polymer-modified cementitious overlay over a 20-year-old exposed-aggregate pool deck. The concrete contractor originally finished the deck by seeding select aggregate into the fresh concrete and then removing the top mortar layer using a broom with a water-spray attachment.

aggregates from crushed concrete, grinding drywall scraps, to use as soil amendment at the site. c) Promoting „„deconstruction‟‟ in place of „demolition‟. d) Deconstruction means planned breaking of a building with reuse being the main motive.
Factors such as deleterious materials in aggregates, aggregate coatings, coarse aggregate fracture faces, shape and texture, and testing limitations may prevent higher strength from being achieved. Final concrete mixture proportions are determined by trial batches either in the laboratory or by small size field production batches. The production, transportation, placement and finishing of high ...
Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates.
Cleaning Exposed Aggregate Concrete in Preparation for Sealing. How to thouroughly clean exposed aggregate concrete: Exposed aggregate concrete by nature will gather dirt, dust, and debris and get dirtier as time passes.
TOP-STOP is a spray-applied, water-soluble surface retarder designed to slow the set of surface mortar in concrete to expose the aggregate. It temporarily halts the set of Portland cement at the surface while the concrete below the surface cures normally.

Concrete is recycled by using industrial crushing equipment with jaws and large impactors. After the concrete is broken up, it is usually run through a secondary impactor and is then screened to remove dirt and particles and to separate the large and small aggregate.
Exposed aggregate finishes are popular as a slip-resistant surface and as an attractive decorative touch to a concrete surface. The growing use of retarders to achieve them has paralleled other advancements in decorative concrete technology - first there was utilitarian use of retarders as admixtures for concrete pours in extreme or hot conditions, then use as a surface application on the top ...
The required properties of the lightweight concrete will have a bearing on the best type of lightweight aggregate to use. If little structural requirement, but high thermal insulation properties, are needed then a light, weak aggregate can be used. This will result in relatively low strength concrete.
