This work investigates the use of Cocoa Pod Husk Ash (CPHA) as an additive in sandcrete block production. The effect of CPHA addition on compressive strength of locally produced sandcrete blocks from three different sources within Osogbo was investigated at 1, 2, 3, 4 and 5% CPHA replacement by weight of cement.

The aim of this paper is to evaluate the quality of sandcrete block production in Owerri, Imo state, Nigeria with its compliance to NIS 2007. Specifically to determine the water absorption rate of hand moulded sandcrete block produced by block making industries, evaluate the compressive strength of the hand moulded sandcrete blocks and to …
Sandcrete Blocks are usually made with cement and Sharp sand. In Nigeria, the most popular cement makers include Dangote, Elephant, Unicem and the …
To solve this problem, Nigerian Industrial Standard (NIS 87:2007) which is a standard reference document for manufacturing of sandcrete blocks in Nigeria; specifies the minimum characteristics ...
The compressive strength values of the sandcrete blocks ranges from 0.81N/mm 2 and 1.25N/mm 2 which when compared with NIS, was found to be below the minimum requirement of the NIS; 2007. Inadequate mix ratio was observed to be one of the factors of poor quality sandcrete block production in the area.
The first standard for sandcrete block in Nigeria was developed in 2000. It was reviewed in 2004 and the latest review was done in 2007 from which NIS 87:2007; Standard for sandcrete blocks emerged as the latest standard reference document for sandcrete block production in Nigeria (NIS, 2007).
This paper highlights the huge opportunities in the small-scale sandcrete block making industry in Nigeria. It explains the ingredients whose understanding is necessary for engaging in the profitable and sustainable small–scale sandcrete block making business. These ingredients include the available resources, material requirements, the basic …
This study investigates the use of Saw Dust Ash (SDA) as partial replacement for ordinary Portland cement (OPC) in sandcrete blocks. Some units of sandcrete hollow blocks were produced by partially replacing the cement content with 5% to 25% by weight of SDA, using vibrating block moulding machine. Sandcrete blocks without SDA serve as the control. …

It is on this bases that the study assessed the quality of sandcrete block produced with river sand in order to determine their compliance level to the standard expected of a sandcrete block in Nigeria. Eighteen sandcrete blocks of size 225 mm 225 mm 450 mm were gotten from three different production locations in Ifo, Ogun State Nigeria.
The aim of this research is to determine the properties of sandcrete hollow blocks produced by block industries in Nigeria, particularly in Idah, Kogi State by assessing the compressive strength and water absorption …
Sandcrete block is a major building material in Nigeria. This research assessed the quality of blocks produced in Adeta, Ilorin West Local Government Area of Kwara State, Nigeria.
A survey was conducted of the various block moulding firms within south east Nigeria to determine the mode of production of blocks, mix ratios nature/quality of sand and the structural ...
Nigeria Abstract The production of sandcrete blocks using groundnut shell ash (GSA) as cement replacement was investigated. Six number sandcrete blocks were cast for each replacement levels (0, 10,20,30,40, and 50 percentage) with GSA.
The aim of this study is to assess the quality of commercial Sandcrete blocks produced in Minna metropolis, Niger State, for compliance with existing standards: Nigerian Industrial Standard and ...
The mechanical properties of sandcrete block greatly influenced the durability of structures built from it. This study was carried out to assess the compressive strength of sandcrete blocks produced in two major …
Sandcrete blocks have been in use throughout Nigeria and in many parts of the world for a very long time. The prominence of sandcrete blocks as part of the local building materials that make up ...
This study assessed the production management practice being adopted in the manufacture of quality sandcrete blocks in selected sampled parts of Owerri municipal, Imo State, Nigeria.
The problem of non-uniformity in the sandcrete blocks production process practiced across the broad spectrum by manufacturers and the desire to improve profit in the face of dwindling resources and inflationary …
It is concluded that sandcrete block in the South West part of Nigeria are of lower standard as a result of factors such as poor workmanship, mix ratio and method of curing, experience and skill of production crew etc, contributes to the poor quality of Sandcrete blocks and this made our blocks unsuitable for load bearing walls.
It has been reported by some researchers that sandcrete blocks are the major masonry units used in Nigeria's construction industry, accounting for more than 90% of the country's physical infrastructure. As a result, sandcrete blocks are important components in building construction. They …
