Aggregates such as sand and gravel are mixed with cement and water to form concrete. There are several key properties of aggregates including being clean, hard, durable, and having a shape that provides good workability and strength. The most common aggregate sources are river stones or crushed rock. Proper grading of aggregate sizes is important to prevent voids when mixed. Concrete is formed by mixing aggregates, cement, and water. The exact proportions and mixing process affect the workability and strength properties of the resulting concrete. Curing the concrete is also important for the hardening and strength development process.

Solution
1. Following criteria should be take into consideration while selecting materials for construction
a) When selecting building materials, it is important to consider the aesthetic appeal, initial and
ongoing costs, durability and availability of the material. Look for materials that will not
compromise the environment or run out in the future.
You will, therefore, need materials that come from renewable or replaceable sources, materials
that can be recycled and are in abundant supply.
b) The best way to choose construction materials that will fit your needs is by considering the
durability, maintenance, aesthetic and cost of each material to be used.
Following factors should be considered while selecting materials for construction :
Recyclable
Best materials are those that can be reused because they will reduce the need for new materials
to be produced in the future. How materials are installed and fixed can have an effect on the
ability to reuse them, so the shorter the expected life of the building, the greater should be the
reliance on screw or bolt fixing rather than adhesive and other permanent fixings.
Availability
It is advisisble to choose material that is easily available. “Having to import material has
potential for delivery delays resulting in project hold-ups thereby increasing costs,”
Ease of installation
“Sometimes people are attracted to a certain material without considering the complications
involved in its installation,” Before you commit to a particular material, find out how easy it is to
install, because you might end up incurring more costs from wastage resulting from the
installation process.
Durability
Your materials should be able to adapt to the weather and conditions they are exposed to. “Some
materials deteriorate rapidly, especially in a wet environment. So it is essential that materials
selected have the durability required fo.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can

Mortar & Mixing
- 1. •Explain the main functions of a good mortar mix • State how good workmanship will improve the sealing properties of a mix • Calculate mortar quantities for walling areas Lesson Objectives
- 2. Mortars Generally Mortar fulfills a number of functions. These include: It cements the bricks together to provide stability - and solidity, while holding them apart to spread loads evenly. It compensates for irregularity between units when straight, level and plumb walling is laid. It also seals any gaps to resist wind or rain penetration. As well as its gap-filling adhesive function it is required to have durability and strength to suit the application. It also contributes to the aesthetic qualities of the wall.
- 3. Three important Functions Mortars should have: 1. good workability 2. sufficient resilience to accommodate long term thermal movement of the masonry 3. adequate bond strength 4. good resistance to water penetration
- 5. Mortar is made from fine aggregate (usually sand) and a binding agent (nowadays usually cement). When mixed with water a chemical reaction, called hydration, occurs and the mortar sets. Early mortars were usually based on lime and sand but they were very slow to set and readily absorbed rain water (the mortar set through a process known as carbonation where the lime gradually hardened by absorbing carbon dioxide from the atmosphere). Mixing On Site
- 6. Requirements of a Good MortarRequirements of a Good Mortar • Adequate compressive strength • Adequate bond strength • Durability:- resistance to frost and chemical attack •Joints sealed against, wind driven rain LONG LIFE REQUIREMENTS WORKABILITY Bricklayers require a “fatty” mortar which hangs on the trowel without being sticky, spreads easily and stiffens neither too quickly nor too slowly.
- 12. Modern mortars use cement as the main binding agent although hydrated lime (ie bagged lime) is often introduced into the mix to give it a more plastic feel and to make it more ‘workable’. Lime also improves the mortar’s ability to cope with thermal and moisture movement. Mixed Ready for Use
