Construction Chemicals Enumeration

9 Chemical categories

Are the chemicals or ingredients added to cement during the process of manufacturing of cement in industry

5 Types of cement additives

reduces friction and increase flow property

example of a dispersant

controls the loss of fluid

example of a fluid loss agent

control free water and solid from settling

decrease gas mobility in cement paste during liquid to solid transformation

example of gas migration additive

Increases slurry density

examples of weighting agent

Ingredients in concret other than cement, water and aggregates

3 reasons for using admixtures

9 types or classification of concrete admixture

reduces water content at least 5%

material of water reducer

retards setting time

material for retarders

accelerate setting time and early strength development

material for accelerator

improve workability and durability in freeze thaw

material for air entrainers

decrease air content

material for air detrainers

Increase bond strength

material for bonding admixture

reduce water-cement ratio, and increase flowability of concrete

material of super plasticizers

reduce drying shrinkage

material for shrinkage reducers

reduce steel corrosion activity in chloride laden environment

material for corrosion inhibitor

chemicals that are used to repair damaged secton or member of any concrete structure

5 Classification of concrete repair

these are supplied as a ready t use blend of dry powder

3 primary groups of resin based repair systems

used for injecting into cracks, honeycomb, and cavities in concrete structures.
can also be used for grouting base plates with very narrow gaps

range (mm) for injection materials

3 types of resins used for injection

the partial or complete wearing away, dissolving, or softening of any metal substance by chemical action

2 types of corrosion management

3 types of anticorrosive coating

anticorrosive coating that is impact, corrosion, and abration resistant

anticorrosive coating that is used for corrosion and weathering coat for steel

anticorrosive coating that is a high gloss top coat for epoxy and inorganic zinc

Substance that is applied to an environment that significantly reduces the corrosion rate of materials

increasing load carrying capacity of structural members particularly increase in live load/ traffic loads is expected
used to repair damaged structure due to corrosion, earthquake, fire etc.

used to protect new or repaired concrete surfaces from future chemical attack

5 types of concrete/ protective coatings

any finish material applied over a floor structure to provide walking surface

6 types of flooring coating

flooring coating made from epoxy resin, achieving a sleek, high-gloss appearance and a flat and level surface

flooring coating made from epoxy or polyurethane that protects concret from oil and chemical spillages

flooring coating made from vinyl ester resin and epoxy thate protects against aggressive acods, alkalis and solvents including sulfuric, nitic and hydrochloric acid, ethanol, butane and methanol

flooring coating made from polyurethane that is resistant to high temperature, abrasion and impact

flooring coatingthat is a state of the art technology

flooring coating made from silicon carbide and is used in the finishing of floors to make the surface slip and wear resistant

a particle form composition made in size graded to be used in mixing cement to give extra hardness to concrete floor without affecting cement chemistry

foor hardener made out of sodium silicate, magnesium, or fluor silicate that is used to seal the concrete surface permeability and a good shiny appearance

foor hardener made out of metal alloy and quartz aggregate that is used to increase durability, better aesthetic, good abrasion, resistance and less dust

used in a variety of application sucha as repair of cracks, fill seams between tiles, and for stabilizing soil

5 materials used for grouting

generic terms relating to steel studs, bolts and anchorages which are bended into a substrate

3 different types of chemical anchoring

Also known as glue, cement, mucilage, or paste is any non metallic substance applied to one surface or both surfaces of two separate items that bind them together and resists their separation

3 classification of adhesive

natural, compounded or synthetic materials used to "enhance" the joining of individual memebers of a structure without employing mechanical fasteners

2 main types of bonding agents

4 types of bonding agents used in the construction industry

used in grouting the gaps between tiles

3 types of tile grout

a material that has the necessary adhesive and cohesive properties to form a seal is seal is sealant

7 Types of construction sealants
