produces less environmental pollution during manufacturing process; disadvantages of bricks. time consuming construction; cannot be used in high seismic zones; since bricks absorb water easily, therefore, it causes fluorescence when not exposed to air; very less tensile strength; rough surfaces of bricks may cause mold growth if not properly cleaned
disadvantages: 1. a messy process, requiring additional work to clean up. 2. if oxalic acid is included in the powder, it can cause etching or blistering of marble and limestone depending on the skill of the person using it. 3. requires equipment (i.e., a floor machine, wet vac, mop, mop bucket, etc.). grinding with diamonds. advantages: 1.
4. advantages of ready mixed concrete – rmc. good quality concrete of uniform consistency under controlled conditions is produced. faster concreting is possible due to the automatic and continuous operation of the manufacturing ready mix concrete plant. supervision and labour costs can be reduced. the storage of cement is eliminated.
production process of ready mix concrete structural concrete normally contains one part cement, two parts fine mineral aggregates, and four parts coarse mineral aggregate.these proportions, however, are often varied to achieve the strength and flexibility required for a particular setting.
advantages and disadvantages of ready-mix concrete. materials are combined in a batch plant, and the hydration process begins at the moment water meets the cement, so the travel time from the plant to the site, and the time before the concrete is placed on site, is
the dry process requires much less fuel as the materials are already in a dry state, whereas in the wet process the slurry contains about 35 to 50 percent water. in the wet process, the drying process is fuel consumption. here, below you can read both “wet” and “dry” process in detail. 1. wet process

the process of harvesting stone and then crushing it down to size requires the use of natural resources and mechanical processing. when unwanted concrete is recycled, you’re giving new life to the aggregate in a way that involves very little processing and leaves natural materials untouched.
the following are the advantages of concrete : availability of concrete ingredients easily. easy handling and moulding of concrete into any shape. easy transportation from the place of mixing to place of casting before initial set takes place. ability to pump/spray to
this type of precast concrete manufacturing is employed for specific jobs that last for a short span of time. the locally available labor force is, as for as possible, used, and the equipment and molds are rented. generally, the work is carried out in open space. although this has some economic benefits, there are a few disadvantages: 1.
disadvantages of precast concrete. there are some disadvantages to precast concrete.they are discussed below. high initial investment: for installing a precast concrete plant, heavy and sophisticated machines are necessary which requires a high initial investment.a large scale of precast construction projects must be available to ensure sufficient profit.
following are the disadvantages ready-mix : the materials are batched at a central plant, and the mixing begins at that very plant. so the travelling time from the plant to the site is critical over longer distances. some sites are just too far away, which can risk that ready mix may become unusable due to setting.
advantages of precast concrete process. precast concrete process provides following advantages: structural efficiency; flexibility in use; optimum use of materials; speed of construction; quality consciousness; adaptability; protection of the environment; advantages of precast concrete construction. precast concrete construction is less expensive than real brick.
manufacturing process the manufacturing process of transparent concrete is almost same as regular concrete. small layers of the concrete are poured into the mould and on top of each layers, a layer of fibres is infused. fabric and concrete are alternately inserted into moulds at intervals of approximately 2 mm to 5mm. 7.
one of the overlooked disadvantages of using insulated concrete forms is that the houses built in this way can be challenging to remodel later on down the road. you’ll need to think carefully about the design of the structure since you can’t add a new door or a window without cutting through a concrete wall to make that happen.
some of the disadvantages of precast concrete include: transportation. it can be complicated to move precast concrete to a jobsite. the weight of the concrete can do damage to many types of trucks, and it is important to keep it stable so that the concrete pieces are not compromised.
concrete raw materials extraction and processing. - landscape degradation ( see examples) - dust and noise. - visual impact on some areas of outstanding natural beauty. - proximity to population centres. - loss of agricultural land.
suspended floors have been benefiting from lightweight concrete for years, as it reduces the weight on the structure and increases fire resistance. because lightweight concrete is typically thinner, it is made of different ingredients from traditional concrete
downgrading of quality of concrete. increase in water absorption capacity ranging from 3% to 9%; decrease in compressive strength of concrete (10-30%) reduces workability of concrete. lack of specifications and guidelines.
concrete floor is easy to clean and the maintenance cost of concrete floor is very less. 7. fire resistance. the concrete being non-combustible material, this flooring offers a fire-resistant floor, required for fire hazardous buildings. disadvantages of concrete flooring. defects on concrete floors are not easy to rectify.
disadvantages: its disadvantages are as follows: 1. as the sections of the structure are heavy, they need more space. thus the use of concrete as shielding against radiation needs more space. 2. the weight of shielding concrete is very high in the range of 3360 to 3840 kg/m 3. aggregates to be used in shielding high density concrete:
advantages / disadvantages. high-strength concrete resists loads that cannot be resisted by normal-strength concrete. not only does high strength concrete allow for more applications, it also increases the strength per unit cost, per unit weight, and per unit volume as well.
one of the biggest advantages to choosing recycled concrete over virgin materials is that you’ll save a good chunk of money. because fewer natural resources are utilized and less time is involved in the production process, you will see an immediate dip in price.
selection of concrete depends on various factors like environment, energy consumption, budget and technical aspects. hence the concrete technology stepped towards the development of alternative building material which can fulfil these aspects and are locally available so as to reduce the cost of construction.
removal, cleaning, finishing and inspection processes; casting: advantages. casting can be used to create complex part geometries, including both external and internal shapes. some casting processes are capable of producing parts to net shape. (no further manufacturing operations are required to achieve the required geometry and dimensions of the parts.)
advantages of precast concrete. the concrete of superior quality is produced as it is possible to have better technical control on the production of concrete in factory. it is not necessary to provide joints in the precast construction. the labour required in the manufacturing process of the precast units can easily be trained.
there are many different types of precast concrete forming systems for architectural applications, differing in size, function and cost. the advantages of using precast concrete is the increased quality of the material, when formed in controlled conditions, and the reduced cost of constructing large forms used with concrete poured on site.
the workability of the concrete: the less workable the mix, the longer it must be vibrated. the energy put in by the vibrator: bigger vibrators do the job faster. the
