Asphalt cement sticking to the aggregator is somewhat more complicated than a new asphalt cement. This is primarily due to the effect of asphalt on atmospheric oxygen during use and weathering. A typical range of particle size distribution for reduced asphalt coating.

Physico-mechanical properties of restored asphalt coating. Asphalt cement consists of predominantly high molecular weight aliphatic hydrocarbon compounds, but also small concentrations of other materials, such as sulfur, nitrogen and polycyclic hydrocarbons with a very low chemical reactivity. Asphalt cement is a combination of asphaltenes and maltentes. Asphalt are more viscous than resin or oils, and play an important role in determining the viscosity of asphalt.

The oxidation of the pressed asphalt causes the oil to convert into resins and resins to convert into asphalt, which leads to hardening and more viscous binder. Rogers. "Ontario's experience with restored materials for use in aggregates." Presented at the International Conference of the Road Federation, Calgary, Albert, Magni.

Roughly speaking, this is usually allocated to free-member and cohesive bulk materials. Depending on the product available various brands, basic colors or bulk materials, such as sand or sand.

Building materials for decorative design - Now check the availability of the desired products!

To make your choice, select the perfect and ready-to-use product for your project and insist the quality of such properties such as frost and resistance to weathering, as well as effective efficiency against weeds. Basal split is an example of a bulk material that is suitable not only for practical construction projects, such as the substructure on terraces, but also very attractive for decorative purposes. Take a look at our wide range of various bulk materials and make sure that the versatility of the products.

Varieties and application

Alacata solution for dissolution must perform a plurality of quality criteria to withstand all external adverse effects. A ready-to-use solution for plastering, which you can use for the water permeable grout of plaster surfaces, for example, in the garden, inlet or on the terrace, is convinced of its resistance to atmospheric influences and high load capacity. The volumetric material is resistant to abrasion, effectively prevents the formation of weeds in the joints and easily transfers random driving vehicles.

Groups of gravel products and sand. Here you will find an explanation of various groups of products, from the production of gravel and sand. Since the applications of sand in the construction sector are diverse, there is also a number of terms in which the specific sand fitness is expressed directly.

Building plaster and sands are used. For the production of construction gravel and sands from gravel and sand sand from a sediment, raw materials are processed by washing and seven. During the washing process, separated components are removed, such as IL, clay, clay or woodcase particles. At sifting, the resulting material is divided into different grain size classes, which are then used as needed.

This includes, for example, frost resistance and thawing agents, a fraction of the swelling components of organic origin, the content of water-soluble chlorides or the content of separated components. Gravel and sand for road, deep and road construction, the construction of landfills.

The cuttings are either deliveries that do not meet the increased requirements for noble slabs, or all the delivery, at which the bottom and upper nominal screen width are not directly nearby. They can be made by direct screening or by assembling neighboring grains.

Table of the most important scales of units and individual scales

If several chips are combined. Your crane is a high-quality large block that will provide you with constant availability. Density indicates. How harder is heavier or lighter than the water of the same body. Concrete blocks apart: hollow block with recesses.

Precast beams for solid ceilings. Round concrete pipes without legs. Wastewater and septic tanks. The wire ropes of the wiring harnesses must be laid when: the braid is damaged, strong wear is noticeable, corrosion scars appear, there are folds, wrinkles or fuses, teeth, butt damage or clamp are detected.

Stop cable should also not be used if one of the two next numbers of visible wires is detected in the worst point. Chains should not be used in lifting, if. A whole chain or a member has an extension of 5% or more, or a chain or part of it is rigid, or the initial thickness of the limb decreased by more than 10% anywhere. Ropes and chains should not be loaded beyond their maximum permissible load.

Calculation of the seal coefficient

In the case of stop ropes and chains with more than two threads, only two threads can be considered reference. When using stop ropes and chains as possible permissible loads Must be calculated in accordance with the appropriate angle of inclination. Invalid tilt corners of more than 60 °. In such cases, it is necessary to always take into account the carrying ability of one thread.

When lifting items with sharp edges, the ropes and chains must be protected from damage using mild intermediate layers, such as wood. If stretch cables and chains are diverted several times around the load, the windings must lie close to each other without intersecting.

When using lifts, use ropes that do not twist. Plastic shells or coated cables should not be used. Loads should not be loaded by lifting ropes. The formation of cable loops should be avoided. Bending ropes at the edges or on rollers of small diameter reduces load capacity. In such cases, cables with higher bearing capacity should be used. With a strong frost load bearing capacity significantly decreases. Wire ropes must be protected from humidity.

Care I. maintenance Also include lubricant. Heavy contaminated cables must be cleaned from time to time. Wire ropes must be checked at regular intervals to ensure their operational safety. Special attention should be paid to parts of the ropes that pass through cable pulleys or which are located near the pendants of the rope or rope devices.

Weight rails of tower rotational road systems

Chains should not be tied. Before use, twisted chains must be rotated. Turning chains should not be repaired, clinging together with wire or with the help of the wire. Screws are held together. It is intended for applications in which special requirement is not required.

It is used in all types of work for which special cement is not required, namely. Pre-mixed concrete precompanied and reinforced concrete structures Paving, runways and bridges Channels and water pipes Prefabricated blocks and elements Brickwork cement floor. Due to its excellent workability, rapid evolving resistance and high resistance is especially recommended.

Heavy concrete concrete in the marine environment Concrete sidewalks in general and, in particular, those placed on high-performance equipment, and those that have quick transit qualifications. Constructions with sliding formwork concrete during periods of low temperature. . To achieve solutions and concrete with sufficient strength, durability and volume stability, it is recommended to strictly follow all current specifications using.

Use well-balanced, clean and secure units. To avoid using aggregates with a delayed shape and very small sands, as they increase the need for water in mixtures, which reduces the resistance and impermeability of the solution or concrete and increases the risk of cracking.

It is recommended to use as much water as possible, for which it is vital to use the plasticizing additive of the average radius of action and avoid using very liquid mixtures, since it reduces the resistance and impermeability of the material and increases the risk of cutting cracks.

Reducing construction terms Rapid on to be preloaded before and after load.

• Increase security if the dosage is saved.
• Increase durability by reducing the porosity of the paste.

This is a granular material of inorganic, natural or artificial origin, intended for construction purposes. The main function of the unit is the creation of a solid concrete frame with a minimum interval. We distinguish the aggregates depending on their origin, bulk density, size and grain size.
