How do you dispose of Portland cement?
You should be able to spread a low concentration of unmixed portland cement over soil that needs to be more acidic, just as you would use ground limestone. You can use a home soil test kit; in many areas, the county extension service will test your soil for a reasonable fee. The major constituents of portland cement are either materials (sand/silica) that don't affect soil chemistry or alkaline substances that reduce acidity. Many cements have gypsum which some people recommend adding to soil that is high in salt or low in calcium. Research has shown that dust from portland cement kilns is about as effective as ground limestone at reducing soil acidity. http://hubcap.clemson.edu/~blpprt/acid5.html. See http://ohioline.osu.edu/hyg-fact/4000/4026.html for recommended application rates (use the crushed limestone rate as an approximation, but realize the cement will reduce the acidity of the soil much more quickly). You could spread up to five 80-pound bags over a 0.2 acre yard. Three cautions - 1. Cement can burn skin and plants until it's reacted with water. Apply it using the same precautions you would use in handling cement for mixing and avoid putting excessive amounts on lawns or desirable plants. If you have children or pets that could come into contact with the dust, if the wind is likely to blow the dust into areas where people or animals are, if you've applied it on grass or ground cover, or if you plan to work in the area right after applying, wet the area with a hose after spreading. It's a good idea to do this in any case. 2. The cement will affect the consistency of different soils differently. If you mix too much cement with soil that has a lot of clay, the mix may become like concrete. If you have any concerns, spread the cement over the area at half the recommended application rate (25 pounds per thousand square fee). 3. Some specialty cements will have different ingredients. You can find out what the ingredients of a particular brand are from the Material Data Safety Sheet (MSDS). Quikrete publishes its MDSDs at http://www.quikrete.com/OnTheJob/SpecData.asp.
1 Explain the managerial roles and managerial skills?
Managerial Roles According to Mintzberg (1973), managerial roles are as follows: 1. Informational roles 2. Decisional roles 3. Interpersonal roles 1. Informational roles: This involves the role of assimilating and disseminating information as and when required. Following are the main subroles, which managers often perform: a. Monitor-collecting information from organizations, both from inside and outside of the organization b. Disseminator-communicating information to organizational members c. Spokesperson-representing the organization to outsiders 2. Decisional roles: It involves decision making. Again, this role can be subdivided in to the following: a. Entrepreneur-initiating new ideas to improve organizational performance b. Disturbance handlers-taking corrective action to cope with adverse situation c. Resource allocators-allocating human, physical, and monetary resources d. Negotiator - negotiating with trade unions, or any other stakeholders 3. Interpersonal roles : This role involves activities with people working in the organization. This is supportive role for informational and decisional roles. Interpersonal roles can be categorized under three subheadings: a. Figurehead-Ceremonial and symbolic role b. Leadership-leading organization in terms of recruiting, motivating etc. c. Liaison-liasoning with external bodies and public relations activities. Management Skills Katz (1974) has identified three essential management skills: technical, human, and conceptual. Technical skills: The ability is to apply specialized knowledge or expertise. All jobs require some specialized expertise, and many people develop their technical skills on the job. Vocational and onthejob training programs can be used to develop this type of skill. Human Skill : This is the ability to work with, understand and motivate other people (both individually and a group). This requires sensitivity towards others issues and concerns. People, who are proficient in technical skill, but not with interpersonal skills, may face difficulty to manage their subordinates. To acquire the Human Skill, it is pertinent to recognize the feelings and sentiments of others, ability to motivate others even in adverse situation, and communicate own feelings to others in a positive and inspiring way. Conceptual Skill : This is an ability to critically analyze, diagnose a situation and forward a feasible solution. It requires creative thinking, generating options and choosing the best available option.
