What Can I Do For You?
the ideal concrete mix to use for constructing a driveway should have at least a 4,000 psi compressive strength, a water-cement ratio of 0.50, aggregates no larger than 1-inch in size, and a slump thickness of 4 to 5 inches. in colder climates, the mixture should have an air-entrainment value of 6%. driveways often are subject to the elements
cement : sand : gravel 1 : 2 : 5 for grade c15 (general purpose concrete) = 2175 psi = 152 kg/m2; gen. 2000 psi 1 : 2 : 4 for grade c25 (strong) = 3625 psi = 255 kg/m2; generally 4000 psi 1 : 2 : 3 for grade c30 (very strong) = 4351 psi = 305 kg/m2;generally 4500 psi
this gives you a basic 4500 psi concrete mix ratio of: 1 part cement; 2.26 parts stone 1.73 parts sand; rounded off it's basically a 1 : 2 : 2 concrete mix ratio. if i break the weights down per cubic yard of concrete, it comes to: 1. 702.5 pounds of cement. 2.
of 1:3:3 – on 1 part cement, 3 parts sand with 3 parts aggregate produces with a compressive strength of 3000 . on water with the three ingredients, a paste is formed that binds them together till the gets hardened.

ecocrete represents the state of the art in the worldwide thrust of cemex to develop products that reflect our concern for economic viability and ecological well-being, while providing optimum flexibility for every construction application.. ecocrete produces and designs a wide range of ready-mix concrete products which provide high strength and resistance against varying environmental conditions.
high strength concrete mix ratio; different grades of concrete denotes its strength for required construction. the “m” denotes mix. for example if the concrete mix is of m20 grade then the compressive strength will be 20 mpa. so, what is 20 mpa here ?? 20 mpa is expression or unit to show compressive strength of cmr (concrete mix ratio).
you need a 5,000-psi mix with a 5% air content, and you need to be able to strip the products from the forms in 15 hours. historically, for similar mixes, you’ve used 555 pounds of cement and 120 pounds of fly ash per cubic yard of concrete.
this concrete mixture ratio of 1 part cement, 1 parts sand, and 3 parts aggregate will produce a concrete mix of approximately 2500 to 3000 psi. mixing water with this cement, sand, and aggregate will form a paste that will bind the materials together until the mix hardens.

we measure a concrete’s compression in pounds per square inch (psi). most concrete compositions have a psi range of between 2,500 and 5,000. putting it into practice: let’s use this in an example, for m5 concrete, the mixing proportion would be 1: (cement) 5: (sand) 1: (coarse) 0: (aggregates).
a ratio of 0.8 makes concrete wet and fairly weak concrete. normal compressive strengths when concrete is properly cured are: 0.4 w/c ratio –> 5600 psi; 0.8 w/c ratio –> 2000 psi. for example, if the water-cement ratio is 0.50 for concrete and cement is added is about 50 kg (weight of 1 bag of cement) water required for concrete will be,
nominal mix ratios for these concrete mix are 1:2:4 for m15, 1:1.5:3 for m20 etc. standard mixes or ratio the nominal mixes as mentioned above for cement aggregate ratio would result in wide variation of strength and also could lead to over or under-rich mixes.
super 5000 concrete mix description pakmix® super 5000 concrete mix is a specially formulated blend of portland cement, sand and gravel ideal for use where a thickness of 2' or greater is required. it is a high strength, 5000 psi, contractor grade formula. all ingredients are thoroughly premixed to ensure maximum strength and workability
recommended concrete mix proportions the key to achieving a strong and durable concrete is mixing the ingredients in proper proportion. typically a concrete mixture should have the following proportions of the ingredients: cement content: 10 to 15% aggregates and pebbles: 60 to 75% water: 15 to 20 percent entrained air: 5 to 8 percent.
quikrete® 5000 concrete mix commercial grade concrete mix designed for higher-early strength gain. achieves 2500 psi in 3 days and 5000 psi in 28 days. ideal for cold weather application. use for: • concrete projects 2” thick or more that require high strength • driveway aprons • patios • curbs
it plays a major role in creating a strong, durable concrete block. the major materials needed in the preparation of concrete blocks are portland cement, sand, aggregate (stone), and water. you can calculate the concrete mix ratio by entering the width, height and depth of the ratio in this concrete mix ratio calculator to know the total volume, sharp sand, gravel and water.
step 6: determine water requirement the amount of water to be added to the mix is a function of the nominal maximum aggregate size and required slump. example: 4500 psi at 28 days w/c ratio = 0.44 mas = 1.5 in. nominal mas = 1.0 in. 6.0% air slump = 1.5 in. 265 lb. water/cubic yard.
concrete des for 5000 psi satisfac with results exhibiting an average strength of 5733 psi. both the slump and air content were within anticipated tolerances. conclusions & recommendations the mix design used in this investigation is satisfactory for field use provided rigid control be maintained relative to slump and air content.
prescribes a standard concrete mix ratio that he thinks will produce the required concrete. he may also indicate the type and size of aggregate to be used. the builder/site engineer prepares the mixes based on the ratio that has been prescribed. 2.1.3 designed mixes in these mixes the
his name is ali nazari , he developed an concrete mixture which withstands 60000 psi when normal concrete is 5000 and french lafarge ductal concrete is. capaple of 20000 psi and very expensive and shipped from france. only you have to do is to add 20 grams of nanopowder per 1 kilogram of concrete and steel fibers and plastic fibers, 1 kilogram

the 5000 psi, as has been stated might be needed for durability and then a maximum water/cement ratio comes along with that. but for structural computations, we are missing looking as shear and deflection. shear is typically based on the square root (sqrt) of the compressive strength. the sqrt of 5000 psi is 71 psi and the sqrt of 4000 psi is 63.
