Batching, Mixing, Placing and Compaction of Concrete
Batching is the process of measuring concrete mix ingredients either by volume or by mass and introducing them into the mixture. Traditionally batching is done by volume but most specifications require that batching be done by mass rather than volume. Percentage of accuracy for measurement of concrete materials as follows.When the quantity of cement to be batched exceeds 30% of scale capacity, the measuring accuracy should be within 1% of required mass. If measuring quantity is less than 30%...
The Advantages of Crossbreeding
Mar 31, 2012 · The advantages of crossbreeding are well documented and can have a big impact on your net return. Heterosis (hybrid vigor) and breed complementarity are the primary benefits realized from a properly planned crossbreeding program.

What Are the Advantages and Disadvantages of Agriculture?
Apr 16, 2020 · Much of the destruction of the rain forests is due to the expansion of agricultural operations. Removing old-growth plants and trees can also increase erosion, remove nutrients from the soil and spur flooding. The dust storms that plagued the Midwest in the 1930s were, in part, due to over-farming of the land and clearing of natural plant cover.
What Are Plants Made Of? | Ask A Biologist
Feb 05, 2015 · Water, which can make up to 95% of the weight of a plant, enters the plant through its roots. Carbon, which makes up the most of the rest of the plant, comes from the air and enters the plant through holes in its leaves. Oxygen from carbon dioxide, and hydrogen from water, enter through the leaves and roots, and are used to make glucose.
