You are working on a concrete mix design that requires each cubic yard ofconcrete to have 0.45 water–cement ratio, 1165 kg/m3 of dry gravel, 4% air content, and 335 kg/m3 of cement. The available gravel has a specific gravity of Ggravel = 2.7, a moisture content of 1.6%, and absorption of 2.4%. The available sand has a specific gravity of Gsand = 2.5, a moisture content of 4.8%, and absorption of 1.5%. For each cubic meter of concrete needed on the job, calculate the mass of cement, moist gravel, moist sand, and water that should be added to the batch. Summarize and total the mix design when finished (don’t include air entrainer in summary).

➤ GOAL: Design a concrete mixture for the following specifications • Plain concrete interior beam •Required average 28 day compressive strength of the concrete, f'c = 30 MPa Exposure Condition: Very Mild (protected from cold weather, chemicals, etc) •No admixture needed TYPE I PORTLAND CEMENT Specific Gravity (SG) 3.15 FINE AGGREGATE (natural sand) Bulk dry SG 2.64 Fineness Modulus 2.80 Moisture Content (MC) op 6% Absorption Capacity (AC) 0.7% COARSE AGGREGATE (well graded gravel, some crushed) Bulk dry SG 2.70 Dry-Rodded Unit Weight 1600 kg/m³ Nominal Maximum Size Aggregate 37.5 Moisture Content (MC) SSD 0.5% Absorption Capacity (AC) 1.3%
Note:hand written solution should be avoided.
Calculate the weight of cement that should be in a batch if the design mix requires concrete to have water-cement ratio of 0.45, dry gravel of 1258 kg/m3, water of 122 kg/m3 and 6% of air content. Use the following: Gravel Specific Gravity = 2.65 Moisture Content = 2.5% Absorption = 4% Sand Specific Gravity = 2.42 Moistur Content = 2.17% Absoprtion = 1.86 % Select the correct response: 253.16 kg/m3 O 122 kg/m3 395.56 kg/m3 271.11 kg/m3
PROBLEM 1 Given the following parameters, design a Concrete Mix Design ACI Method Required average strength will be 28MPa with slump of 75 to 100mm. The coarse aggregate has a nominal maximum size of 25 mm and a dry-rodded mass of 1900kg/m'. Other properties of the ingredients are: Cement Type I specific gravity 3.15 Coarse aggregate bulk specific gravity 2.75 absorption 3% Fine aggregate bulk specific gravity 2.68 absorption 1.2 % fineness modulus 3 Adjustment for Aggregate Moisture: Tests indicate total moisture of 5 percent in the coarse aggregate and 8 percent in the fine aggregate.
I need answer within 20 minutes please please with my best wishes
Consider the following data for concrete with mild exposure Water-cement ratio = 0.50 Water 191.6 litre The required cement content will be (a) 561 kg/m³ (b) 472 kg/m³ (c) 383 kg/m³ (d) 294 kg/m³
Choose the correct answer from the followings Use ACI method to design a concrete mix which is required to obtain f'c28 = 34.5MPa and a slump of 75mm . The fineness modulus of the aggregate is 3.0 , the bulk density of coarse aggregate is 1600 kg/m² and the maximum size is 25. Both the specific gravity of fine and coarse aggregate are 2.68. neglect the absorption and total moisture content . 1- The W/C ratio is * a-0.74 b-0.48 c-0.57 d-0.61 2- The cement content is * 420 kg/m3 240 kg/m3 204 kg/m3 402 kg/m3 3- The carse aggregate content is * 1140 kg/m3 1004 kg/m3 1040 kg/m3 1400 kg/m3 4- The fine aggregate content is * 807 kg/m3 780…
