Find the weight (in kg) of cement, water, flyash, fine and coarse aggregate to produce a cement/flyash mix for pumped concrete, using the British Method that has a characteristic 28-day compressive strength of 45 MPa. One hundred laboratory test results on the controlling mix show a standard deviation of 5.3 MPa (k=1.65). The exposure classification for durability purposes is A2 and the conditions require a fly ash/ high early strength cement blend (with a 40% proportion of fly ash). The specific gravity of the crushed coarse 20 mm aggregate to be used is 2850 kg/m³ and its dry rodded density is 1600 kg/m³. The specific gravity of fine aggregate is 2750 kg/m³ and its fineness modulus is 2.5. Assume the high early strength cement density is 3150 kg/m³ and fly ash density to be 2000 kg/m³

You are part of a Design and Construct team for a conference centre and 300 bed hotel accommodation in Darwin, Northern Territory. The site is 10 hectares on the oceanfront. The developer wants the project to be environmentally friendly and to minimise energy consumption and water usage while maintaining a luxury hotel feel. List the factors and strategies that you would consider most important in the design of this building, i.e. the design adaptations for the building.

Explain the term ‘sound attenuation.’ What factors are most important when considering sound attenuation requirements of a party wall

Find the weight (in kg) of cement, water, flyash, fine and coarse aggregate to produce a cement/flyash mix for a column, using the British Method that has a characteristic 28-day compressive strength of 60 MPa. One hundred laboratory test results on the controlling mix show a standard deviation of 6.0 MPa (k=1.65). The exposure classification for durability purposes is A1 and the conditions require a fly ash/ high early strength cement blend (with a 40% proportion of fly ash). The specific gravity of the crushed coarse 20 mm aggregate to be used is 2850 kg/m3 and its dry rodded density is 1600 kg/m3. The specific gravity of fine aggregate is 2750 kg/m3 and its fineness modulus is 2.7. Assume the high early strength cement density is 3150 kg/m3 and fly ash density to be 2500 kg/m3

What is meant by the term building envelope and why is there a need to understand how the construction sector adapts the building envelope

Briefly explain the general growth pattern of bacteria indicating the names of phases.

A concrete mix was designed for a concrete road pavement (i.e. heavy mass concrete). A 28-day strength of 26 MPa is required. The exposure classification for durability purposes is C. One hundred laboratory test results on the controlling mix show a standard deviation of 5.3 MPa (k=1.65). The density of crushed coarse aggregate is 2850 kg/m³ and its dry rodded density is 1600 kg/m³ and the maximum size to be used is 10 mm. The specific gravity of fine aggregate is 2750 kg/m³ and its fineness modulus is 3.0. The high early strength cement used has a density of 3150 kg/m³.

Find the weight (in kg) of cement, water, fine and coarse aggregate for this mix, required to make a 0.25 m high x 3.6 m wide x 12 m long concrete pavement using the ACI Method.

Construction Safety

1.You overhear the following conveconstruction rsation between two employees: First employee: “I’m not going to work in a trench. How do I know it won’t cave in on me?” Second employee: “Don’t be ridiculous. It’s just as dangerous on the surface as it is down there.” What do you think about this conversation? Is either of these employees right? Wrong? What would you tell these two employees about working in excavations?

2. “Come on Jones,” said the carpenter. “I’ve been using ladders since I was a kid. I don’t need training on how to use a ladder.” “Yes, you do,” responds the supervisor. “You might know how to use a ladder, but you don’t know how to use one safely. You’re going to attend the training just like the rest of us.” Is ladder training really necessary, or is OSHA just being intrusive and overly cautious?
