There are no specific studies on the estimation of lightweight concretes slump using artificial intelligence systems, and most researches are on slump of conventional concrete. In the present study, we use an adaptive neuro-fuzzy inference system ANFIS (Sogeno Fuzzy Inference System) tool to estimate the slump and density of LWAC.
Retempering of Concrete Made by using Artificial Sand Containing Superplastciser & Retarder - written by Sachin Kavathe, J. G. Kulkarni published on 2015/03/26 download full .
The present invention relates to the use of blood in the construction and building industry, whereby blood and extracts of blood containing haemoglobin are used as air entraining colloids. The recommended process for preparing a lightened material consists in associating a construction element chosen from the cements, mortars and concretes, with at least one air entraining colloid chosen from ...
Should You Use a Sand Infill For Artificial Grass? We Reveal the Truth The question of whether you should use a sand infill for artificial grass is one that has been hotly debated in the industry over the past few years. Historically, artificial grass was developed for use in sports pitches as groundsmen were
Test results indicated that the highest mechanical properties were achieved for HSC with 20% ASA. Using ASA extended the cracking time of the HSCs and resulted in finer cracks associated with the lower free shrinkage. Moreover, there was a marked decrease in the autogenous shrinkage for all HSCs including artificial aggregates.
PDF | The paper Present the study of replacement of natural sand with artificial sand in concrete conventionally concrete is a mix of cement sand and aggregate there is a large variation in the ...
Benefits of using sand infill for artificial grass. Durability: This is one of the most obvious reasons. Sand is durable and will contribute quite a lot to the well-being of your artificial grass. It's especially helpful in high-traffic areas and will keep the natural look and feel of the grass for many years.
Two types of typical concretes widely used in Syria (in Damascus and Aleppo) and four other types of concretes, using aggregates from different regions, have been prepared. The shielding properties of these six types were studied for gamma ray (from Cs-137 and Co .
Retempering of Concrete Made by Using Artificial Sand Author : S. S. Patil and A.R. Pethkar Volume 1 January-June 2012 pp 6-8 Abstract. Adding water to a plastic mix to increase slump is an extremely common practice, even though it is not recommended because it increases the porosity of concrete.
Oct 24, 2017· Oftentimes, artificial turf for sports fields will have rubber infill because of its shock-absorbent abilities. Sand, though, provides those same shock-absorbing qualities while providing additional benefits. Though several types of infills exist, sand proves to be the best type of infill thanks to its durability, absorbency, and versatility.

Both concrete made using artificial sand and natural sand are moderate to chloride permeability. In water absorption test we observed after 24 hours curing, the increase in weight of both natural sand and artificial sand blocks are less than 3% that means both concrete are low absorber hence concretes .
5 Important Artificial Grass Installation Tips There are several different methods that can be used when it comes to artificial grass installation. The correct method to use will depend upon the site on which the grass is being installed. For instance, the methods used when installing artificial grass on to concrete
However, many people in India have doubts about quality of concrete / mortars when manufactured or artificial sand are used. Manufactured sand have been regularly used to make quality concrete for decades in India and abroad. Pune - Mumbai expressway was completely built using artificial/manufactured sand. Issues with Manufactured Sand
Apr 08, 2006· Contrary to this pronouncement, our recent linguistical study and new translation of Latin author Vitruvius' book De Architectura (1st Century B.C.) states that the magnificent quality of Roman concrete resulted from the extensive use of artificial pozzolanic mortars and concretes. Two artificial pozzolans were intensively manufactured:
Both concrete made using artificial sand and natural sand are moderate to chloride permeability In water absorption test we observed after 24 hours curing, the increase in weight of both natural sand and artificial sand blocks are less than 3% that means both concrete are low absorber hence concretes,...
Apr 11, 2018· The objective of this study is to examine the workability and various mechanical properties of concrete using artificial lightweight aggregates produced from expanded bottom ash and dredged soil. Fifteen concrete mixes were classified into three groups with regard to the designed compressive strengths corresponding to 18 MPa, 24 MPa, and 35 MPa.
