Influence of GGBS on Mechanical Properties of Low Traffic Concrete Paver BlocksAbdulRazakBH
Abstract: Supplementary cementitious materials (SCM) are the integral part of modern concrete with significant enhancement
in concrete performance. Low cost of production, low heat of hydration along with improved mechanical properties encourage
the replacement of ordinary Portland cement (OPC) with SCMs to a greater extent. The study focusses on influence of Ground
granulated blast furnace slag (GGBS) as SCM in production of concrete paver blocks. Compressive strength, split tensile
strength, and flexural strength are the properties under consideration. Improved compressive strength and flexural strength was
observed in blended concrete with 20% and 40% GGBS replacement levels.
Keywords: GGBS, M-Sand, Paver Blocks, Split tensile strength, Flexural strength

Experimental Study on Concrete with Waste Granite Powder as an AdmixtureIJERA Editor
Granite fines which are the byproduct produced in granite factories while cutting huge granite rocks to the desired shapes. Granite fines are used as a filler material in the concrete, replacing the fine aggregate which will help in filling up the pores in the concrete. Filling up of the pores by granite fines increase the strength of the concrete and also a material which is abundantly to investigate the strength behavior of concrete with use of granite fines as an additive. Concrete is prepared with granite fines as a replacement of fine concrete in 4 different propositions namely 2.5%, 5%, 7.5% and 10% and various tests such as compressive strength, split tensile strength and flexural strength are investigated and these values are compared with the conventional concrete without the granite fines. It was observed that substitution of 7.5% of cement by weight with Granite fines in concrete resulted in an increase in compressive strength for both 7 & 28 days to 33.14 & 43.40 N/mm2 compared to 23.26 & 39.41 N/mm2 of conventional concrete. Tensile strength too followed a similar pattern with a 7.5% substitution with granite fines increasing the tensile strength for 7 & 28 days to 2.87 &4.19 N/mm2 compared with a 2.4 & 3.4 N/mm2 of conventional concrete. However flexure strength of 7.5% granite fine replacement exhibited a good improvement of flexural strength for 28 days to 6.34 N/mm2compared to a 3.35 N/mm2 of conventional concrete. Further investigations revealed that to attain the same strength of conventional concrete a 10% substitution with granite fines is effective. So it can be concluded that when locally available granite is a good partial substitute to concrete and improves compressive, tensile and flexure characteristics of concrete, while simultaneously offsetting the overall cost of concrete substantially.

Self-compacting concrete is high performance concrete which is highly flowable, non-segregating, spread on its
own weight and doesn‟t need any compaction. This paper deals with flow and strength characteristics such as
compressive strength, split tensile strength, flexural strength and impact strength of Self-compacting concrete
with various percentages of waste plastic fibres like 0%, 0.25%, 0.5%, 0.75%, 1.0%, 1.1%, 1.20%, 1.3% and
1.4% is added by weight of cement. The mix proportion for M40 grade of concrete was done by using Nan Su
method (Cement: GGBS: Fine aggregate: Course aggregate 1: 0.705: 3.34: 2.62). Water powder (W/P) ratio
0.36, cement content 280kg/m3
, GGBS 220 kg/m3 was calculated and maintained as constant throughout the
experimental work for all eight mixes, only the superplastizers dosage was varied for different percentage of
fibres. In this experimental investigation one control mix and eight (8) different mixes were considered. Totally
81 Cube, beam, Cylindrical specimens and square plates were casted, cured and tested as per IS specifications.
For determining impact strength drop weight method was used. The results obtained indicate that fresh
(workability) characteristics satisfy the lower and upper limit as suggested by EFNARC. The tests on hardened
properties indicate that the compressive strength, split tensile strength, flexural strength was improved
proportionally with the addition of waste plastic fibers upto 1.0% by weight of cement and then decreases. The
impact strength improved proportionally with addition of fibres upto 1.2% by weight of cement and then
decreases

Self compacting concrete for slip form pavingeSAT Journals
Abstract Slip form paving has been extensively used worldwide for construction of pavements. During the process of paving, concrete mix with a slump less than 50 mm is placed in front of a paver. Because of the low consistency of the mix, a great deal of vibration is needed to move entrapped air and compact the concrete. There is a need to overcome problem by designing a concrete that would not require vibration to compact the concrete mix, at the same time stability after extrusion and high flexural strength. Mix design based on the absolute volume concept was adopted to fabricate SFSCC. Volume of paste of 0.38 and water content of 200 kg/m3 was kept constant throughout the study. Cement content was varied from 360 to 425 kg/m3, 3 mixes of SCC with GGBS (SFSCC-S), 3 mixes of SCC with 2% of alccofine replaced by cement (SFSCC-SA) and 3 mixes of SCC with 2% of metakaolin replaced by cement (SFSCC-SM) is reported. The quantity of polypropylene fibers used in all the mixes was 900 gm/m3. Slump, spread, green strength and compaction factor were evaluated for all the 9 mixes. To simulate the practical construction process, a mini paver system was fabricated. The strength parameters compressive and flexural strength of concrete was evaluated at 7 days and 28 days. Keywords: Slip form paving, alccofine, SCC, GGBS, metakaolin, SFSCC, SP.

The Coupled Effect of Nano Silica and Superplasticizer on Concrete Fresh and ...IJMER
The The effect of individual and combined additions of both nano silica (NS) and
polycarboxylate-ether superplasticizer (SP) admixtures on concrete mixes were studied. Twenty concrete
mixes were prepared, keeping the water/cement ratio constant at w/c = 0.40, with different amounts of
SP admixture, and NS. the superplasticizer was studied in the range of (0 – 0.88)% (over cement weight),
nano silica additions were tested at (0 – 3.00)% range (over cement weight). Early, and late
compressive strengths, as well as results of fresh concrete (slump) test of formulations were evaluated by
means of design of experiments, in order to identify the primary factors and their interactions on the
measured properties. The most desirable NS and SP % were determined. The results showed that
regardless of the used NS percentage, the higher compressive strength results were reached at, or
around SP observed saturation dosage (0.66% by weight cement). The statistical approach applied here
enabled to develop relations, which could adequately describe the dependency of both the compressive
strength, and slump on the composition of NS, and SP concretes. These relations were presented as
contour plots, which from a practical point of view could serve as a basis for mix design

DESIGN OF RIGID PAVEMENT AND ITS COST-BENEFIT ANALYSIS BY USAGE OF VITRIFIED ...IAEME Publication
A country can achieve sustainable and rapid growth in all fields by improving its connectivity and transit systems. Connectivity of people to resources by improved transit mechanism results in improved living standards. Apart from other means, the major part of connectivity of any country is through road systems. Well designed and maintained pavements provide better and long lasting service. In India, all the major road systems are designed as flexible pavements only, because of their ease of construction and less time it takes to be opened to traffic operations. The major problem with flexible pavements is their design life and high maintenance costs. Also, globally reducing petrol reserves, which are used for bitumen and asphalt production are also increasing the need for alternatives. To tackle these problems, rigid pavements can be constructed. Although the cost of construction of rigid pavements is high, its long life, high load carrying capabilities and low maintenance cost will balance the initial cost aspect. Recently, many studies are being conducted on different pozzolanic admixtures which can be used as partial replacement of cement in rigid pavements, thereby reducing its cost and enhancing properties of the mix. Here, an attempt is made to reduce the construction cost of rigid pavements by incorporating Vitrified Polish Waste (VPW) as partial cement replacement in proportions of 5% for M40 grade concrete. Further, to enhance flexural properties of pavement, Recron fibre is added to optimum VPW in increments of 0.1%, then after C.C pavement is designed for two lane two way national highway and cost benefit analysis is performed.
