Elaborate/explain the scope and significance use in ASTM c70 - standard test method for surface moisture in fine aggregates
Design a concrete mix for the following conditions and constraints using the absolute volume method:Design EnvironmentBuilding frameRequired design strength = 27.6 MPaMinimum dimension = 150 mmMinimum space between rebars = 40 mmMinimum cover over rebars = 40 mmStatistical data indicate a standard deviation of compressive strength of 2.1 MPa is expected (more than 30 samples)Only air entrainer is allowedAvailable MaterialsAir EntrainerManufacturer specification 6.3 ml/1% air / 100 kg cementCoarse aggregate19 mm nominal maximum size, river gravel (rounded)Bulk oven dry specific gravity = 2.55, Absorption = 0.3%Oven dry-rodded density = 1761 kg/m3Moisture content = 2.5%Fine aggregateNatural sandBulk oven-dry specific gravity = 2.659, Absorption = 0.5%Moisture content = 2%Fineness modulus = 2.47
determination of moisture content and surface moisture of aggregates is a method to determine wether the material is good or not, what is the essence of this methods in construction? Explain.
UUURRRGGGEEENNNTTT PLEASE You are working on a concrete mix design that requires each cubic yard of concrete to have a 0.43 water–cement ratio, 2077 lb/yd3 of dry gravel 244 lb/yd3 of water, and 4% air content. The available gravel has a specific gravity of Ggravel = 2.6, moisture content of 2.3% and absorption of 4.5%. The available sand has a specific gravity of Gsand = 2.4, a moisture content of 2.2% and absorption of 1.7%. Air entrainer is to be included using the manufacturers specification of 0.1 fl. oz / 1% air / 100 lb cement. For each cubic yard of concrete needed on the job, calculate the weight of cement, moist gravel, moist sand, and water that should be added to the batch. Summarize and total the mix design when finished.

The design of a concrete mix requires 1173 kg/m3of gravel in dry condition,582 kg/m3of sand in dry condition, and 157 kg/m3of free water. The gravelavailable at the job site has a moisture content of 0.8% and absorption of1.5%, and the available sand has a moisture content of 1.1% and absorptionof 1.3%. What are the masses of gravel, sand, and water per cubic meter thatshould be used at the job site?

Civil Read properly Q- Membersof the ACI Building Code committee conducted a study, and the results showed that the scatter in the modulus of elasticity did not support the use of a different or "more precise" formulation. As a result, the equation (Eci) can be applied generally. Calculations should be based on project mixture design test results if a project calls for a more exact estimation of the modulus of elasticity. Where f 0 ci is the strength of the concrete at the moment of transfer in psi and wc is the unit weight of the concrete in pcf, which is often taken to be 160 pcf for precast concrete and 150 pcf for cast-in-place concrete. Members with post-tension tensioning sequence affects elastic shortening in post-tensioned members. Tendons may be stressed to a maximum of 0.80 fpu, however the stress in the tendon right after seating must be 0.70 fpu or less. Calculate the fES for elastic shortening losses.
Two batches of concrete cylinders were made with and without a calciumchloride (CaCl2) accelerator admixture. Six cylinders were made of each batch andsubmerged in water for different times before testing for compressive strengthand the results are shown in Table P6.35.It is required to do the following:a. Using an Excel sheet, plot the relationship between curing time andcompressive strength of the two mixes on the same graph. Label all axesand curves.b. Comment on the effect of the accelerator on the compressive strength ofPCC at early and late ages.
