Different Types of Aggregates Used in Road Construction: Classification of aggregates based on Grain size: 1.Fine Aggregate: The aggregate with grain size below 4.75 mm is termed as fine aggregates. There are many different types of aggregates available on the market, each with its own unique properties. In contrast, aggregates with lower specific gravity can be porous, weak, and highly water absorptive. thickness is less than 3/5th of its mean dimension are termed as flaky aggregate. Aggregate definition and Shape, Types, Properties - Civil Knowledges 2) irregular aggregate:- it is a irregular in shape and size, due to irregular shape their void is increased and good for cement bonding and concrete making. Light weight aggregate ( bulk density ~ 1200 kg/m, Medium weight aggregate ( bulk density ~ 1520 kg/m, Heavy weight aggregate ( bulk density ~ 2080 kg/m. Join now! The fineness of sand determines the proportion of sand in the concrete mix. After the concrete is completely dry, it has excellent compressive strength. It includes both the fine aggregate and coarse aggregate. Irregular or partly rounded: It has 35-37% voids which is useful for medium quality concrete. In the case of fine aggregates, the density of aggregate considered along with the volume of voids or empty spaces between the particles. Aggregate types on the basis of shape there are four types of aggregate on the basis of shape 1) rounded aggregate 2)iregular aggregate 3)angular aggregate 4) flaky aggregate 1) rounded aggregate:- it is round in shape you know that due to water flow in river and sea natural sand is deposited on the bank of of river and Sea shore. 1) natural aggregate:- It can be empirically calculated by adding the cumulative percentage of sample of an aggregate retained on each of specified series of sieve, and dividing the sum by 100. Cleanliness: Aggregates must be free of impurities and deleterious substances that are likely to interfere with the process of hydration, prevents affection bonding between the aggregates and the matrix. It is used to fill the voids in between the coarse aggregates in concrete so as to increase the resistance against crushing. Angular: It has 38-41% voids which is best for concrete. Although some variation in aggregate properties is expected, characteristics that are considered include: grading; durability; particle shape and surface texture Igneous rock. 2.

Coarse aggregates are prepared manually or mechanically. 2) generally aggregate is made from crushing and grinding of igneous rocks metamorphic rocks and sedimentary rocks. It reduces the shrinkage of binding materials and hence cracking of mortar during setting is avoided. Whether you are planning to construct roads, bridges, walkways, or buildings, these seemingly insignificant rocks are a lot more important than you think. At the same time, sedimentary rocks provide soft to hard, porous to thick, and light to heavy aggregates. These are combined with binding material such as cement or asphalt to produce different varieties of concrete or mortar. fine aggregates: aggregate particles that pass through a 4.75 mm sieve or aggregates with size less than 5 mm. Frost resistance, Fire resistance of aggregate, shape, surface texture, water absorption . maximum size is 75 mm. The other properties of iron depend on the amount of carbon it contains. The type of lightweight aggregate and its volume fraction in a mix determine the density of lightweight concrete. Sedimentary rock. Asphalt Concrete. The types of aggregates have little effect on flexural strength, however other researchers claim that higher strength coarse aggregates produce more flexural strength than low strength aggregates. Cement The mineralogical composition of aggregate affects its crushing strength, hardness, elastic modulus, and soundness which, in turn, influence various properties of hardened concrete containing the aggregate.

Different Types of Aggregates Used in Road Construction: Classification of aggregates based on Grain size: 1.Fine Aggregate: The aggregate with grain size below 4.75 mm is termed as fine aggregates. There are many different types of aggregates available on the market, each with its own unique properties. In contrast, aggregates with lower specific gravity can be porous, weak, and highly water absorptive. thickness is less than 3/5th of its mean dimension are termed as flaky aggregate. Aggregate definition and Shape, Types, Properties - Civil Knowledges 2) irregular aggregate:- it is a irregular in shape and size, due to irregular shape their void is increased and good for cement bonding and concrete making. Light weight aggregate ( bulk density ~ 1200 kg/m, Medium weight aggregate ( bulk density ~ 1520 kg/m, Heavy weight aggregate ( bulk density ~ 2080 kg/m. Join now! The fineness of sand determines the proportion of sand in the concrete mix. After the concrete is completely dry, it has excellent compressive strength. It includes both the fine aggregate and coarse aggregate. Irregular or partly rounded: It has 35-37% voids which is useful for medium quality concrete. In the case of fine aggregates, the density of aggregate considered along with the volume of voids or empty spaces between the particles. Aggregate types on the basis of shape there are four types of aggregate on the basis of shape 1) rounded aggregate 2)iregular aggregate 3)angular aggregate 4) flaky aggregate 1) rounded aggregate:- it is round in shape you know that due to water flow in river and sea natural sand is deposited on the bank of of river and Sea shore. 1) natural aggregate:- It can be empirically calculated by adding the cumulative percentage of sample of an aggregate retained on each of specified series of sieve, and dividing the sum by 100. Cleanliness: Aggregates must be free of impurities and deleterious substances that are likely to interfere with the process of hydration, prevents affection bonding between the aggregates and the matrix. It is used to fill the voids in between the coarse aggregates in concrete so as to increase the resistance against crushing. Angular: It has 38-41% voids which is best for concrete.
