Design the concrete mix according to the following conditions: Design Environment Pavement slab, Bozeman, Montana (cold climate) Required design strength = 3000 psi Slab thickness = 12 in. Statistical data indicate a standard deviation of compressive strength of 250 psi is expected (more than 30 samples). Only air entrainer is allowed. Available Materials Air entrainer: Manufacture specification is 0.15 fl oz/1% air/100 lb cement. Coarse aggregate: 2 in. nominal maximum size, crushed stone Bulk oven-dry specific gravity = 2.573, absorption...

Q) Design the concrete mixture for the slab
2. A reinforced slab concrete foundation is to be poured for a building. The building is to be constructed near Edmonton. The slab will be in direct contact with the soil, and the soil typically has a sulphate content of 0.3 percent by mass. The minimum rebar spacing in the slab is 100 mm. The contractor is certain that his workers can place a concrete with a...

5. A sample of aggregate has a moisture content of 10 percent. Its absorption capacity is 4 percent. What is the weight of free water in a 100-1b sample of this aggregate? How is fineness modulus measured and what does it represent The specific gravity and bulk density of an aggregate are 2.6 and 95 pcf respectively. Find the loose (bulk) volume of a 190-lb sample. A sample of fine aggregate with a specific gravity of 2.6 has a bulk...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
