Many specifications require mockups for vertical concrete formed surfaces, regardless of whether or not for structural or architectural concrete. For instance, Section 18.104.22.168 of ACI 301-10, “Specifications for Structural Concrete,” contains a requirement for providing a mockup of structural concrete surface appearance and texture.
When I was reading we ran into the question “How thick should a concrete floor be?”.
The standard concrete garage floor is six inches thick and, with use of proper control joints, should be thick enough to withstand normal use. Type of Use. How thick you pour your concrete floor can be determined by how the floor is going to be used. Heavy, medium use, and light use in addition are a few additional things to pay attention too.
How thick should concrete floor be?
Standard concrete floor slab thickness in residential construction is 4 inches. Five to six inches is recommended if the concrete will receive occasional heavy loads, such as motor homes or garbage trucks. To prepare the base, cut the ground level to the proper depth to allow for the slab thickness.
A slab is defined as a member where the panel dimension is not less than 5 times the overall slab thickness. Eurocode 2 states minimum thickness for floor slabs in buildings is 125mm. Other countries may use different minimums depending on their national standards. However, if there is any reinforcement.
What is the minimum depth for a concrete slab?
Minimum slab thickness for house:– using some basic thumb rules, regulation and guideline as per ACI code and IS code 456:2000, for concrete floor, minimum concrete slab thickness for house is kept 4 inch (100mm), providing minimum concrete grade M10 to M15 and mesh bar should be embedded in concrete, 2″ deep from top of floor slab.
Proper slab thickness is determined by: Compressive strength. Tensile strength, affected by the presence or lack of reinforcement. What is being placed on the patio. The weight of the concrete slab itself. The size of the pad in square feet.
The best way to calculate how much concrete you will need in cubic yards is to do the following: Mark your area that needs concrete and divide it into smaller areas. Calculate the volume of your area after determining its shape (see the examples below) by multiplying it with the thickness of the concrete. Convert the volume from feet to cubic yards to get a precise number of concrete that you need – in cubic yards.
What are the ACI 301-10 requirements for a mockup of concrete?
For instance, Section 22.214.171.124 of ACI 301-10, “Specifications for Structural Concrete,” contains a requirement for providing a mockup of structural concrete surface appearance and texture. For both an SF-2.0 and SF-3.0 surface finish, a mockup is specified. The ACI 301-10 requirements for SF-2.0 and SF-3.0 are as follows:.
Surface void sizes, projection heights and surface tolerance requirements, described objectively by measurement limits, are ideal for approving mock-ups. Many specifications require mockups for vertical concrete formed surfaces, regardless of whether or not for structural or architectural concrete.
Should I use new or used form materials for the mockup?
Constructing the mockup with used forms is more realistic. Even if the mockup is small, always use concrete from two truckloads to provide a batch-to-batch color variation in the approval process.
