Interlocking concrete paver driveway. Pavers come in a number of styles, shapes and tones. Pavers manufactured from concrete go well with flag, brick and concrete walkways or patios. Concrete pavers may be used where winter temperatures dip below freezing. They are available in hole, x-shape, y-shape, pentagon, polygon and fan styles.
Sand reinforced polyester composites (SPCs), are building materials with sand acting as reinforcement in the composite.Pioneers in using sand reinforced composites include German business men Gerhard Dust and Gunther Plötner, who made sand reinforced composite bricks with polyester resin and hardener to provide emergency relief housing for those affected by the 2010 earthquake in Haiti.
Permeable pavement surfaces may be composed of; pervious concrete, porous asphalt, paving stones, or interlocking pavers. [1] Unlike traditional impervious paving materials such as concrete and asphalt, permeable paving systems allow stormwater to percolate and infiltrate through the pavement and into the aggregate layers and/or soil below.
Synthetic polymers began replacing other chemical binders for soil stabilization in agriculture in the late 20th century. [1] Compared to traditional chemical binders, polymer soil additives can achieve the same amount of strengthening at much lower concentrations – for example, mixtures of 0.5-1% of various biopolymers have strength levels that match or exceed those of 10% cement mixtures ...

List of some addition polymers and their uses ; Polymer Abbreviation Properties Uses Low-density polyethylene: LDPE: Chemically inert, flexible, insulator: Squeeze bottles, toys, flexible pipes, insulation cover (electric wires), six-pack rings, etc.
Regular concrete is too dense. It is heavy and hard to work. After it sets one cannot cut into it, or nail into it. And it's surface is ugly, cold, and hard in feeling unless covered by expensive finishes not integral to the structure. And yet concrete, in some form, is a fascinating material. It is fluid, strong, and relatively cheap.
Mortar holding weathered bricks. Mortar is a workable paste which hardens to bind building blocks such as stones, bricks, and concrete masonry units, to fill and seal the irregular gaps between them, spread the weight of them evenly, and sometimes to add decorative colours or patterns to masonry walls.
