2. Living building material - Wikipedia

   Rain can supply this water which is an environment that biocement would find itself in. Once introduced to water, the bacteria will activate and feed on the calcium lactate that was part of the mixture. [32] This feeding process also consumes oxygen which converts the originally water-soluble calcium lactate into insoluble limestone.

3. Hydrodemolition - Wikipedia

   en.wikipedia.org/wiki/Hydrodemolition

   Robotic Hydrodemolition in Ystad, Sweden. Hydrodemolition of concrete exposing the rebar.. Hydrodemolition (also known as hydro demolition, hydroblasting, hydro blasting, hydromilling, waterblasting, and waterjetting) is a concrete removal technique which utilizes high-pressure water, often containing an abrasive material, to remove deteriorated and sound concrete as well as asphalt and grout.

4. Papercrete - Wikipedia

   en.wikipedia.org/wiki/Papercrete

   Unlike concrete or adobe, papercrete blocks are lightweight, less than a third of the weight of a comparably-sized adobe brick. Papercrete is generally mold resistant and has utility as a sound-proofing material, however mold can develop if the material remains warm and moist for too long.

5. Concrete degradation - Wikipedia

   en.wikipedia.org/wiki/Concrete_degradation

   When atmospheric carbon dioxide (CO 2), or carbonate ions (HCO − 3, CO 2− 3 dissolved in water) diffuse into concrete from its external surface, they react with calcium hydroxide (portlandite, Ca(OH) 2) and the pH of the concrete pore water progressively decreases from 13.5 – 12.5 to 8.5 (pH of water in equilibrium with calcite).

6. Cement - Wikipedia

   en.wikipedia.org/wiki/Cement

   Fiber mesh cement or fiber reinforced concrete is cement that is made up of fibrous materials like synthetic fibers, glass fibers, natural fibers, and steel fibers. This type of mesh is distributed evenly throughout the wet concrete. The purpose of fiber mesh is to reduce water loss from the concrete as well as enhance its structural integrity ...

7. Superplasticizer - Wikipedia

   en.wikipedia.org/wiki/Superplasticizer

   Their addition allows to decrease the water-to-cement ratio of concrete or mortar without negatively affecting the workability of the mixture. It enables the production of self-consolidating concrete and high-performance concrete. The water–cement ratio is the main factor determining the concrete strength and its durability. Superplasticizers ...

   Using light pressure, work in small sections, starting with the rubber soles. For canvas or leather portions, use extra-gentle pressure to avoid damage. Clean shoelaces separately by running the ...

9. Water reducer - Wikipedia

   en.wikipedia.org/wiki/Water_reducer

   Water reducers offer several advantages in their use, listed below: reduces the water content by 5-10%; decreases the concrete porosity; increases the concrete strength by up to 25% (as less water is required for the concrete mixture to remain workable) increases the workability (assuming the amount of free water remains constant)
