types of concrete & characteristics | concrete classification,the concrete in which common ingredients i.e. aggregate, water, cement are used is known as normal concrete.it is also called normal weight concrete or normal strength concrete. it has a setting time of 30 - 90 minutes depending upon moisture in atmosphere, fineness of cement etc..steel structures vs concrete structures | complete,concrete structure. concrete is the second most used material for construction after water in the world. concrete structure can take compressive stresses very effectively but it cannot take tensile stresses. so the reinforcement is given to concrete where the structure is under the tension load. concrete is widely used in today construction industry today because of its durability and.

explained: cement vs. concrete — their differences, and opportunities for sustainability concrete is the world’s most consumed construction material. yet there’s a lot the public doesn’t know about it or its environmental impact.
there is a difference between foam concrete and aerated concrete, not only in production technology, but also in the technical characteristics of materials. consider these differences: blocks differ in composition: for the production of aerated concrete, lime, sand, cement and water are used, cement, sand and foaming agent are needed for foam concrete.
sidewalks, foundations, and highways are all made of concrete. the main difference between lightweight concrete and normal concrete is the lower density. mass, besides its distinguishable thermal and durability characteristics. in addition, the standard np en 13055-1 defines lightweight aggregate as having a particle.

one of the main advantages of conventional concrete is the self weight of concrete. density of normal concrete is of the order of 2200 to 2600. this self weight will make it to some extend an uneconomical structural material. self weight of light weight concrete varies from 300 to 1850 kg/m3.
the key difference between lightweight and heavyweight concrete is the density of the aggregate. lightweight concrete is made using aggregate whose density is less than 2,100 kilograms per cubic yard (or 131 pounds per per cubic foot), while aggregates with greater densities give rise to so-called heavyweight concrete.
differences between lightweight concrete and normal weight concrete in this 3 minute video, jason explains the differences between lightweight concrete and normal weight concrete. he also discusses drill depth for slabs that dry on both sides.
structural properties compared to that of normal weight concrete. thus, in deciding between lightweight and normal weight concrete, careful consideration should
the density of lightweight concrete in the range between 300 to 1850 kg/cum and normal concrete density 2200 to 2500 kg/cum. lightweight concrete has low density and it helps to reduce dead load of structure as compare of normal concrete. 9. types of lightweight concrete lightweight concrete can be prepared either by injecting
the higher brittleness and lower mechanical properties of lightweight aggregate concrete (lwac) compared to normal weight concrete (nwc) at the same compressive strength has prevented it from
according to emily hopps, associate principal at simpson gumpertz & heger inc., the initial unit cost of lightweight concrete is more expensive than normal weight, “[…] but the unit cost usually is more than offset by the overall reduction in concrete volume and steel tonnage for the structural system.”
lightweight concrete is a mixture made with lightweight coarse aggregates such as shale, clay, or slate, which give it its characteristic low density. structural lightweight concrete has an in-place density of 90 to 115 lb/ft³, whereas the density of regular weight concrete ranges from 140 to 150 lb/ft³.
concrete is used as construction material and it is categorized as normal concrete or high strength concrete based on its compressive strength. the compressive strength of normal concrete is between 20 and 40 mpa. the strength of high strength concrete is above 40 mpa. the high strength concrete has compressive strength between 40 and 140 mpa which is discussed in this article.
normal weight concrete: lightweight concrete: a normal weight concrete is going to be about 140 to 150 pounds per cubic foot: a lightweight concrete is going to be about 90-115 pounds per cubic foot. normal weight concrete has lower water content. lightweight concrete has higher water content.
this concrete is particularly suitable for places where there is a greater chance of frost attack. 4. its unit weight is less than the ordinary concrete but more than the lightweight concrete.
in this code, a lightweight concrete without natural sand is termed 'all-lightweight concrete' and lightweight concrete in which all of the fine aggregate consists of normal weight sand is termed 'sand-lightweight' concrete.' note that though the density is the same there is a difference in design for all-lightweight vs sand-lightweight concretes.
self-compacting lightweight concrete with a binder content of 500–650 kg m23 and a density of 1650 kg m23 was made using less superplasticizer and viscosity modifying agent and a lower water/binder ratio than normal self-compacting concrete. the bulk density was only 75% of normal self-compacting concrete but with a similar compressive strength.
a structural light-weight concrete mix has a density of about 105 pounds per cubic foot compared to normal concrete with a density of 150 pounds per cubic foot. the light-weight concrete density is less because lightweight coarse aggregates and sometimes lightweight fine aggregates are used, which make the concrete weigh less.
by comparison, the dry density of normal weight concrete ranges from 130 to 155 pounds per cubic foot. structural lightweight concrete can be mixed to achieve the same workability, finishability, and appearance of normal weight concrete, as long as it contains enough cement paste to coat each particle and enough fine aggregate to keep the mixture cohesive.
lightweight: cellular lightweight concrete is low on weight and thus it has a positive impact on weight management of building material and craning work. normal concrete on the other hand is very dense and it’s difficult to work on it especially once it sets into a form.
gypcrete vs lightweight concrete. this is for a radiant floor overpour. the gypcrete sights all point out the flaws of concrete, but it seems to me that concrete has the distinct advantage of being mold resistant. this would be an 1 1/2″ slab & if using concrete, i would add fibermesh & an isolation membrane between the crete & the subfloor.
for 3,000 psi, the n-value for normal weight concrete is 9; for lightweight concrete weighing 100 pcf, the n-value is 15; and at 115 pcf, the n-value is 12. in designing with lightweight concrete in composite design, it is recommended that no differentiation be made in n-values for preliminary design only.
