The ingredients of concrete and their proportions are called the design mix Early Use of Concrete The first concrete like structures were built by the Nabataea traders or Bedouins who occupied and controlled a series of oases and developed a small empire in the regions of southern Syria and northern Jordan in around 6500 BC According to ACI code standard concrete grade is categorised according to their compressive strength represented as concrete mix 2000 Psi 3000 Psi 4000 Psi 5000 Psi 6000 Psi 8000 Psi and 10000 Psi For example in concrete mix 2000 numerical figure is compressive strength of concrete is 2000psi 13 8MPa or 13 8N mm2 after 28 days of Mix Design Recommendations When using Top Cast a minimum 3 500 psi concrete mix with a 4 5 slump should be used to achieve correct etch Mixes with more or less cement may yield different results Micro Medium and Deep etches will have different sand and aggregate recommendations for best performance Refer to the appropriate section 🕑 Reading time 1 minuteACI method of concrete mix design is based on the estimated weight of the concrete per unit volume This method takes into consideration the requirements for consistency workability strength and durability This article presents ACI method of concrete mix design Contents ACI Method of Concrete Mix DesignRequired Data Procedure for ACI 3000 PSI 28 Day Aging 6 Rebar 12 in XPR 9 SERIES MODELS 4 1 4 quot 3000 PSI 28 Day Aging 6 Rebar NEVER hand mix your own concrete Download Concrete Slab Requirements 2019 pdf NEW CONCRETE SLAB RECOMMENDATIONS A Study in Lift Design Best Car Lift Guide Top 10 Car Lift Facts Headquarters 1645 Lemonwood Drive

Here are 4 popular concrete mix designs used by most concrete contractors 2500 PSI CONCRETE WITH 3 4 quot STONE MY COST 101 50 PER YARD 3000 PSI CONCRETE WITH 3 4 quot STONE MY COST 105 00 PER YARD 3500 PSI CONCRETE WITH 3 4 quot STONE MY COST 110 00 PER YARD 4000 PSI CONCRETE WITH 3 4 quot STONE MY COST 118 00 One of the best concrete mix ratios is 1 part cement 3 parts sand and 3 parts aggregate this will produce approximately a 3000 psi concrete mix The strength of this mix ratio is good for most concrete slabs footings steps and foundation walls Aug 05 2015 nbsp 0183 32 In my 43 years working with concrete I have never seen a 3000 psi mix used in a structural application I work in infrastructure rather than building but even in building 3000 psi 20 MPa would rarely be used in my experience UK Middle East and Australia In fact it is only allowed in the mildest exposure classification in Australia either 2 500 or 3 000 psi although other values may be specified For example 3 500 psi concrete may be used for improved weathering resistance in particularly severe climates or unusual applications The concrete compressive strength may be Our concrete blocks are made from recycled concrete which holds a strength rating of 3 000 – 4 000 PSI Their strength and size options make them perfect for permanent or temporary outdoor solutions for restaurants special events job sites and so much more

And although concrete is a strong product 3000 to 4000 PSI compressive strength The tensile strength or flexibility of concrete is not as strong So concrete will crack in two if asked to support its self without structural reinforcement For a compressive strength of 3000 psi the lightweight cement content is pounds per cubic yard a 400 590 b 440 560 c 430 560 d 730 750 View Answer light weight and structural light weight concrete lwc mix design aerated concrete concrete cloth hot and cold weather concreting mix design testing methods and new generation 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 Mar 31 2019 nbsp 0183 32 The ideal concrete psi for a given project depends on various factors but the bare minimum for any project usually starts around 2 500 to 3 000 psi Each concrete structure has a normally acceptable psi range Concrete footings and slabs on grade typically require a concrete of 3 500 to 4 000 psi Suspended slabs beams and girders as often The cement content of concrete is of less significance than the w c ratio for structural durability provided the mix is of adequate workability The cement content for a hydropower structure is normally between 220 and 375 kg m −3 Concrete mix design is
