Ask an Expert: how much weight is needed to break concrete ,
Welcome to the Ask an Expert forum , If a block of concrete is just sitting on the ground and you try to crush it by putting weights on top, it can withstand tremendous forc , forces get turned into compression forc A building made of reinforced concrete can actually have a bomb hit it, the concrete cracked into multiple blocks and .
To make concrete though which will greatly extend the volume produced you mix in gravel or sand or crushed brick Proportions are an endless subject of debate but the formula of 1 part cement, 2 parts sand and 3 parts gravel by volume is a good starting point Mix the dry ingredients first and then slowly add water You want "workable" concrete

Well made concrete is very important to protect the steel in reinforced concrete See CHAPTER 17 Reinforced Concrete Strength of concrete in the hardened state is usually measured by the COMPRESSIVE STRENGTH using the Compression Test See CHAPTER 3 Concrete Testing Strength and Durability are affected by:
22—Reinforced concrete Plain concrete (Fig 22) has compressive strength—the ability to resist crushing loads; however, its tensile strength is only about 10% of its compressive strength Its tensile strength is so low that it is nearly disregarded in design of most concrete structur Reinforced concrete is a combination of adequate
Behaviour of Plastic Mixed Reinforced Concrete Columns Under Axial Compression One of the main environmental problem today is the disposal of the waste plastics The use of plastics in various places as packing materials and the products such as bottles, polythene sheets, containers, packing strips etc, are increasing day by day
Crushed recycled concrete can also be used as the dry aggregate for brand new concrete if it is free of contaminants Also, concrete pavements can be broken in place and used as a base layer for an asphalt pavement through a process called rubblization

NPK's Primary/Secondary Concrete Crushers are designed to effectively handle any primary and/or secondary demolition and recycling operation NPK concrete pulverizers easily crush through reinforced concrete and cut through light steel structures allowing material to be separated and recycled, and simultaneously, permits easier handling of material
Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility The reinforcement is usually, though not necessarily, steel reinforcing bars and is usually embedded passively in the concrete before the .
