What is the unit weight of cement mortar?

Between 830kg/m3 to 1650kg/m3 Cement (finely ground gray or white powder used to bind concrete mixtures) weighs between 830 kg/m3 and 1650 kg/m3 (52 lbs/ft3 and 103 lbs/ft3) depending on its handling. The weight of cement that has been pneumatically loaded into a cement silo may be as low as 830 kg/m3 (52 lbs/ft3), while cement that has been stored for a period of time exposed to vibration may be as heavy as 1650 kg/m3 (103 lbs/ft3). It is standard practice to consider a 94 lb bag of cement to be one cubic foot when freshly packed. Two 500-mL beakers were used for 500 grams of dry powdered cement. Cement was simply poured into beaker No 1. Cement was slightly vibrated-imitating consolidation during transport or packing while stored in a silo, into Beaker No 2. An approximately 20% difference in bulk volume was found. This demonstrates the need to measure cement by mass instead of volume for batching concrete.


How much energy is needed to heat 0.7 kg of sand from 10 to 70 degrees Celsius?

To determine how much energy is needed to heat 0.7 kg (700 g) of sand from 10 degrees to 70 degrees C, one first need to know the specific heat of sand. It turns out to be about 0.83 J/g/deg. Thus, to calculate heat needed, use the equation q = mC∆T where m=mass; C=0.83 J/g/deg and ∆T = change in temperature = 60 degrees (70-10). Then q = (700g)(0.83 J/g/deg)(60 deg) = 34,860 Joules. If you want to convert this to calories, it would be 34,860 J x 1 calorie/4.184 Joules = 8,331 calories.


What is 10.9 grade steel?

10.9 grade steel is a common type of high strength structural steel that is typically used in construction and manufacturing applications. The "10.9" refers to the minimum tensile strength in MPa, which is 1000 MPa for the 10 part and 900 MPa for the 9 part, making it a strong and durable material for various purposes.
