What is the relationship between the content of machine-made sand and gravel powder and the fineness modulus?

The main reason is that the machinemade sand particles have more angular edges and the surface is rougher than natural sand With the increase of the amount of machinemade sand the frequency of the machinemade sand surface contact with each other

Product Introduction

Effect of Sand Content on the Workability and Mechanical

Jan 29 2019 The fineness modulus of lightweight fine aggregates and sand were 44 and 22 respectively On the other hand the particles combined by using lightweight fine aggregates and sand exhibited continuous grading which nearly satisfied the standard distribution curves of

aggregate rather than roundedgravel aggregate The most desirable fineaggregate grading will depend upon the type of work the paste content of the mixture and the size of the coarse aggregate For leaner mixtures a fine grading lower fineness modulus is desirable

But it can be solved by sand washing machine The powder content of machinemade sand is fine rock powder less than 0075mm It cannot react with cement hydration but it can have a good relationship with cement crystal stone and it has a microaggregate filling effect in the internal layout In fact if the powder content of the machined sand

What is The Features of Mechanism Sand Washing Machine

At present the general requirement for fineness modulus of manufactured sand is 2630 The sieve size is generally recommended to be 30 mm or 35 mm If the content of stone powder is high 28mm screen can be considered if it reaches about 23 long screen such as 17X5 or 19X5 can be considered Squarehole screen is usually used as

As the moisture content of the wood increases the resistivity decreases by a factor of three for each 1 change in moisture content Wood Modulus of Elasticity Typical stressstrain relationship of wood is linear up to a certain limit followed by a small nonlinear curve after which failure occurs

Machinemade sand is different from the natural sand it is made by making machines and other specific equipments In recent years sand an d gravel market demand shows an

The bigger the fineness modulus is the more coarse the sand is The fineness modulus of the sand used in ordinary concrete is within 37 16And if M x is within 37 31 it is coarse sand if M x is within 30 23 it is medium sand if M x is within 22 16 it is fine sand and if M x is within 1507 it is superfine sand which should be considered specifically when concrete is

According to the fineness modulus MX the specifications of machinemade sand can be divided into 4 types coarse medium fine and extra fine 1 Coarse Sand the fineness modulus is 3731 and the content of particles larger than 05mm exceeds 50 of the

Influence of Manufactured Sand of Different Production

Dry sand production process the stone powder content of manufactured sand is 138 MB value is 05 and fineness modulus is 29 Waterreducing agent polycarboxylic acidbased highperformance waterreducing agent the water reduction rate is 40 the bleeding rate ratio is 20 and the slump retention value 1h is 140 mm

Sep 06 2021 1 First of all it depends on the area where the production line is located the water resources the cleanliness of the raw materials and the specific requirements for aggregate machinemade sand and gravel powder content and fineness modulus

28 What is the relationship between fineness modulus and screen size At present the fineness modulus of machinemade sand is 2630 It generally recommends using a screen size of 30mm or 35mm If the content of stone powder is large consider using a 28 mm screen

Apr 05 2021 Apr 05 2021 Since the stone powder content of machinemade sand is 5 A1 is directly prepared by machinemade sand The other three groups are prepared by sieving 8 11 Stone powder content of machinemade sand A5 is ordinary river sand The fineness modulus of river sand is 27 which is the same as that of machinemade sand Table 4 Mortar mix

Introduction of 12 And 13 Gravel Coarse And Fine sand

1 The machinemade sand produced in the process of crushed stone production has high content of sandstone powder and poor particlelevel matching If the machinemade sand is mixed with natural sand in a ratio of 37 the pumped concrete of less than C40 grade can be well prepared

According to the fineness modulus MX the specifications of machinemade sand can be divided into 4 types coarse medium fine and extra fine 1 Coarse Sand the fineness modulus is 3731 and the content of particles larger than 05mm exceeds 50 of the

28 What is the relationship between fineness modulus and screen size At present the fineness modulus of machinemade sand is 2630 It generally recommends using a screen size of 30mm or 35mm If the content of stone powder is large consider using a 28 mm screen

30 questions about artificial sand and sand making process

Sep 06 2021 1 The sand and gravel contains a large number of particles with critical separation points 2 The sand and gravel contains more flake materials and cannot be screened smoothly 3 The sand and gravel has high mud content 4 The sand and gravel has high moisture content 24 why is the screen mesh easily damaged

Based on a series tests the properties of protomachinemade sand of gravel such as grain feature fineness modulus grading density void ratio and MB value as well as the fineness distribution of stone powder were studied the influences of content of stone powder on these properties of sand and strength of cement mortar were investigated
