Rishabh Lala is a student in the 6th semester at Rajiv Gandhi Technological University in Bhopal. The document discusses various topics related to concrete including its composition, types, properties, testing, ingredients, water-cement ratio, workability, curing, and types of cement. It provides definitions and details on plain cement concrete, reinforced cement concrete, pre-stressed concrete, lime concrete, air entrained concrete, and more.
Pre-stressed concrete uses tensioned steel strands or bars to place concrete in compression and improve its tensile strength. There are two main methods - pre-tensioning, where steel is tensioned before concrete is poured, and post-tensioning, where steel is tensioned after concrete has cured. Pre-stressing counters the effects of tensile stresses from loads and prevents cracking, allowing concrete to act as an elastic material. It provides advantages over reinforced concrete like reduced size, weight, and cracking as well as improved corrosion resistance and shear strength.
This document discusses disruptive innovation theory and provides examples of companies that utilized disruptive innovation strategies. Disruptive innovation theory, proposed by Christensen, involves gaining market share through offering cheaper solutions to new market segments. The document examines how Samsung disrupted Apple's smartphone market by offering affordable low-end Galaxy phones and how Netflix disrupted Blockbuster by developing a new online movie rental and recommendation model. Disruptive innovations can help companies succeed by either targeting a low-end market or creating a new market.
Gartner has developed new metrics to measure data center energy efficiency beyond PUE. The new metrics are Idle Energy (IE), which measures the energy consumed when equipment is idle, and Computational Energy (CE), which measures the energy used for useful computation. IE + CE = Total Energy. Reducing IE improves efficiency. An example shows how improving IE from 56.43% to 49.37% through power capping increased annual useful energy by over 525,000 kWh, saving $55,000. The document recommends using kWh to evaluate efficiencies, reducing IE, and using CE to quantify energy for IT services.
Lightweight concrete uses lightweight aggregates to reduce density. It can be prepared in three ways: by inserting air bubbles, omitting fine aggregates, or using lightweight aggregates. Porous concrete has high insulation and moisture movement but high shrinkage. Lightweight aggregate concrete is used in roofs, walls and precast elements for its strength, low density, and insulation. It has advantages like rapid construction, reduced weight and transportation costs, but disadvantages like water sensitivity, difficult finishing, and longer mixing times.
