How is tamping of fine aggregate different from tamping mortar?
Homework Answers
Solution :
Tamping of fine aggregate is done when only fine aggregate is present i.e dry aggregate, for removing of voids ( air ) entrapped among particles.
Whereas tamping of mortar is done for removing lumps and it is wet tamping.

A bituminous mixture contains 65% coarse aggregate, 35% fine aggregate (by weight of total aggregate) and 4.8% asphalt (by weight of the mixture). Determine the bulk specific gravity of the mixture if, after compaction, it contains 7.0% air voids. Assume that the aggregate absorbs 0.3% of the asphalt by weight of the aggregate. The specific gravities of the materials are: Coarse Aggregate 2.723 Fine Aggregate 2.664 - 1.05

Problem with different moisture conditions: 5. Calculate the quantities of cement, water, fine aggregate, and coarse aggregate per trial mix of 1 m3 for the following specifications. Target mean compressive strength-30 MPa at 7 days; Cement strength class 42.5; Slump required 100 mm; Max. Aggregate size 20 mm; specific gravity of aggregates 2.65% Coarse aggregate UNCRUSHED (10, 20mm), fine aggregate CRUSHED (50% pass 600 micros); Maximum allowable free- water/cement ratio 0.40; Minimum allowable cement content 275 kg/m3; Absorption of fine...

An aggregate blend is composed of 59% coarse aggregate by weight (Sp Gr. 2635), 36% fine aggregate (Sp. G. 2.710), and 5% filler (Sp. Gr. 2.748). The compacted specimen contains 6% asphalt binder (Sp Gr. 1.088) by weight of total mix, and has a bulk density of 143.9 lb/t Ignoring absorption, compute the percent voids in total mix, percent voids in mineral aggregate, and the percent voids filled with asphalt. Assume: V.-1 ft ir Binder Filler FA CA

The question is about the company from both Online and Retail Shop from brick and mortar retailers which both of them have different fixed and variable cost. Given the fact about the differences, it is true that both of them start off with the same break-even point? Both of them have similar Cost Volume Profit Analysis. Online vs brick and mortar retailers companies will have both starts off with the same break-even point?

LAB Using a mortar and pestle, grind approximately 5 g of sodium hydroxide into fine particles. Add 0.50 g of 3,4-dimethoxybenzaldehyde and 0.40 g of 1-indanone to a test tube. Using a vortex mixer, gently mix the two solids together, forming an oil. Add 0.10 g of finely ground sodium hydroxide from Step 1 to the oil. Allow the reaction to sit for 15 minutes. Add 4 mL of 10% aqueous hydrochloric acid. Isolate the product by vacuum filtration. Recrystallize...

A mortar is like a small cannon that launches shells at steep angles. A mortar crew is positioned near the top of a steep hill. Enemy forces are charging up the hill and it is necessary for the crew to spring into action. Angling the mortar at an angle of ?= 54.0 ∘(as shown), the crew fires the shell at a muzzle velocity of 237 ft/s. How far ? d down the hill does the shell strike if the hill...

use (absolute volume method). Calculate the materials (type II cement, coarse aggregate, fine aggregate, and water) needed to make 16 concrete cylinders (diameter = 4", height = 8") for our compression tests. Specified compressive strength = 3000 psi at 28 days. For coarse aggregate, please choose 3/4 in max size gravel containing some crushed particles with the following assumptions: oven-dry specific gravity of 2.68; oven-dry rodded unit weight: 100 lb per cu. ft; moisture content: 1%.
