Abstract

The increased use of concrete for construction purpose has increased the production of cement which indeed releases CO2 causing global warming. Geopolymer concrete (GPC), using activated fly ash instead of cement would be beneficial. Recycled Concrete Aggregate (RCA) from demolished sites as a replacement for conventional coarse aggregate would also be beneficial. In this project, studies have been carried out to understand the effect of 100 percent replacement of cement by fly ash and replacement of conventional coarse aggregate with different levels of RCA, which is 0 to 60% at the variation of 20% under sun curing. Target strength of M30 was achieved for both conventional concrete and GPC with the help of design mix. Hardened Concrete tests such as Compressive strength and Split tensile strength tests at the age of 7 and 28 days were carried out so as to compare the strength between GPC using Recycled concrete aggregate for 0 to 60% at 20% variation.

Keywords: RCA, GPC, Compressive Strength,

1. INTRODUCTION1.1 General

Worldwide increase in construction work leads to demand in cement which in turn leads to global warming. One tonne of OPC production leads to emission of one tonne CO2, which is a major concern at present condition.[Dabhade et al. (2013)]. Due to the scarcity of natural resources, we need a supplementary material to cement and coarse aggregate. Geopolymer concrete is an alternate to conventional concrete wherein cement based binder is replaced with an alternative binder which contains no Portland cement. One type of geopolymer binder is that which contains fly-ash activated by an alkaline solution of sodium silicate and sodium hydroxide. By the production and use of RCA, the advantages include the lower environmental pollution, reduction in valuable landfill space, and savings in natural aggregate resources [Dabhade et al. (2013)]. Partial utilization of Recycled Concrete Aggregate (RCA) along with conventional aggregates with a replacement of cement with fly ash is taken into consideration.

2. ObjectivesThe present study aims to investigate the performance of concrete members

To make use of waste materials like fly ash as binder and partial replacement of recycled concrete as aggregate.

To study the difference in strength of geopolymer concrete by varying the percentage of recycled concrete aggregate used.

3 Materials Used3.1 Cement

Cement is a binder which sets and hardens and binds materials together. The cement available in local market, Ordinary Portland Cement (OPC) of grade 43 as shown in the Figure 1 conforming to the requirement of Indian Standard Specification IS: 8112-2013 is used for preparation of conventional concrete specimen.

3.2 Fly ash

Fly-ash is a by-product of the coal industry. It is a fine particulate material that is produced from the burning of coal and is collected in the electrostatic precipitators of boilers. The size of fly ash ranges from 0.5 µm to 300 µm. Figure 2 shows the view of fly ash.

Figure 1: View of ordinary portland cement Figure 2: View of Fly ash

The type of fly ash used for the study purpose is of class F and its chemical composition is listed in Table 1.

3.3 Recycled Concrete Aggregate (RCA)

Recycled concrete aggregate is collected from demolished buildings and is crushed and sieved to obtain size varying from 12mm to 20mm (Figure 3). The distinctive feature of recycled concrete aggregates is the attached mortar and cement paste on the surface of the original gravels. The percentage of this depends on the degree of crushing and the properties of the original concrete. This attached mortar gives rise to other properties of the aggregates, which are light weight compared to the coarse aggregate, much higher water absorption and poorer bonding capacity and lower abrasion resistance.

3.4 Coarse Aggregate

Coarse aggregate are the particles greater than 4.75mm and angular type are used.

3.5 Fine Aggregate

The type of Fine aggregate used is river sand and well graded passing through 4.75mm IS sieve and retained on 75 micron.

3.6 Water

The water used in concrete plays an important role in the mixing, laying, compaction, setting and hardening of concrete. The strength of concrete depends on the quantity and quality of water used in the mix.

3.7 Additive

Figure 4 shows the view of Sodium Hydroxide used as an additive in the preparation of Geopolymer concrete which helps in activating Fly ash.

Alkaline activator helps in increasing the workability as well as compressive strength. The leaching of Al3+ and Si4+ ions generally high with sodium hydroxide solution compared to that of potassium hydroxide. It helps in controlling the leaching of alumina and silica from fly ash particles, subsequent geopolymerization and mechanical properties of hardened geopolymer.

4 Preparation of test specimenThe concrete moulds are prepared with M30 grade of

concrete. Molarity used in the concrete is 16M. Generally alkaline solution is prepared at least one day prior to mixing of the concrete. Fine aggregate is mixed well to a uniform colour and then mixed with coarse aggregates. Evenly prepared dry mix is then mixed with alkaline solution to get required workability. Mix designs were carried out using Vijaya Rangan (2008), details are given below.

Required quantities of materials were taken according to the predetermined mix design. The GPC moulds are prepared with respect to the achieved design mix. Different moulds taken include Cube, Cylinder and mortar cube. Machine mixing was used for the concrete mix, sand and flyash was thoroughly mixed to form uniform colour. For geopolymer concrete partial replacement of coarse aggregate by recycled concrete aggregate was done. Water was then added as per the water to cement ratio of design mix and well mixed. 2 ml of commercially available Super plasticizer (SP 430) was added per 1 kg of cement. The moulds were oiled so as to prevent sticking of concrete. The mould was filled in 3 layers and being rammed for 35 times with tamping rod. The surface was struck off with trowel and mould was kept for dry for about 24 hours. Specimen were then taken out and cured. Specimens of fly-ash based geopolymer concrete are subjected to sun curing. Tests were conducted at 7 and 28 days.

5 Test Procedures5.1 Preliminary Tests

Preliminary tests of specific gravity test on Coarse aggregate, RCA and Fine aggregate, cement and Flyash were conducted. Sieve analysis tests were conducted for coarse, fine and RCA. Physical tests on cement were

Figure 8: Relation between Split Tensile Strength and % Replacement of CA with RCA

From Figures 7 and 8, following observations are made,

As the replacement level of coarse aggregate with RCA increases, compressive strength decreases. As the replacement level of RCA increases beyond 0% there is a gradual decrease in split tensile strength. For more than 60% replacement case the performance in splitting tensile strength is poor.

CONCLUSIONSBased on the experimental observation and test results following conclusions are made,

1. Specific gravity of RCA is found to be lesser than normal coarse aggregate due to adherence of low density mortar.

2. Characteristic strength of geopolymer concrete is almost equal to that of conventional concrete, hence can be used in construction works.

3. With the increase in percentage replacement of conventional coarse aggregate by RCA, compressive strength gets reduced as it has higher water absorption capacity, reducing water to cement ratio and thereby workability. Also RCA results in decreased interfacial bond within concrete matrix.

4. M30 geopolymer concrete mix with 40% recycled concrete aggregate can be used wherever strength of M30 is required. Hence reduces the cost of construction.

5. Reduction in cement usage can possibly bring economic benefits by reducing cost of construction and also by reducing global warming.

Ramco Super Fast – Rapid Hardening Portland Cement In Precast Units

Precast concrete blocks is increasingly being used in the Indian Construction Industry . Many precast units usually give high importance to factors like quick removal of blocks from the mould and increased production rate.

Keeping the requirements of Precast Industry in mind RAMCO manufactured the RAMCO SUPER FAST –Rapid Hardening Portland cement as per IS 8041 .

The advantages of using precast technology in construction are many. Few of them are as follows :

1. Thermal Efficiency

2. Better fire insulation properties

3. Water Resistance and High Compressive strength

4. Utilisation in light weight blocks which reduces dead loads and decrease in the size of structural components

5. Casting taking place at a centralized plant due to which its easier to implement better quality control procedures thereby enhancing the durability of concrete

6. Concrete can be moulded into any shape and can be customised

7. Rapid execution at site

8. Environment friendly and sustainable as wastage of raw materials are reduced and the casting takes place away from the site
